Well, I know you are in favor of the Peter Parker unmasking because it allows for certain kinds of stories to be told and I'm against it mainly because it damages the "ordinary guy behind the mask" component that's been in place for 40 plus years and is what made Spidey a popular character to begin with, at least we both agree that, sooner or later, it will be undone.
However, here's another problem that I see on the horizon. And that is that Marvel has essentially taken Peter in a direction in which that the only solution HAS TO BE a "mindwipe" of some sort in order to get Spidey back to a point where it somewhat resembles his traditional status quo. And this is going to anger and alienate those who actually like this development, just as they have angered and alienate those that do not. And as a result, those elusive new readers, who are familiar with Spidey based on material other than comics, are going to feel either lost or find that the character of Spider-Man is nothing like what they may have known from those outside sources. If they haven't already.
Sure, this was bound to happen sooner or later that we we're going to get a "everyone now knows Peter Parker is Spider-Man" story eventually; Howard Mackie even said that back in the early 90s, this idea WAS on the table but Tom DeFlaco rejected it because the reaction would've been by the general public in the comic "Who is Peter Parker? I don't care what his real name is. He's still a hero/meance." Also, we will certainly get reactions from Spidey's classic supporting cast which have been all but neglected based on what the writers over on the New Joe's Fridays panel were talking about. Essentially, the storyline is going to go something like this:
1. Peter Parker reveals he's Spider-Man
2. Everyone who ever knew Peter that didn't all ready know this is shocked.
3. Peter Parker becomes a celebrity superhero and the "everyman" symbol for the registration act. The Bugle, much to Jonah's consternation and objections, promotes Spidey as a hero.
4. However, The Daily Bugle begins having credibility problems because of Jonah's past anti-Spidey articles, causing circulation to dwindle; this results in cooperate downsizing in order to keep the Paper afloat.
5. Flash follows Peter around like a groupie, while Aunt May, Mary Jane, and Peter are assigned bodyguards.
6. Peter still teaches, but after the attacks from Doc Ock and Mysterio, the school, under pressure from parents, fires Peter, not wanting to but kids in further danger.
7. Villians led by the Chameleon attempt the first attack on Spidey's family, and fail. This makes Peter regret having ever disclosed his identity.
8. The general public is just as divided over whether or not Spider-Man is a hero or menace, making Aunt May say "I don't understand. Can't they see my nephew is a hero?"
9. Peter begins to see that he may have choosen the wrong side in Civil War due to the various actions committed by the proponents of registration.
10. The Green Goblin, feeling cheated that his arch-enemy has removed his trump card, gathers a group of various villains in a two-proned assult. One against Spidey himself and another against Spidey's family.
11. Unlike the Chameleon's assult, THIS TIME, it results in either Aunt May or Mary Jane being critically wounded, in a coma, and on the verge of death. THIS will be the last straw for Peter, and he quits the registration side. Unfortunately, this makes him in violation of his agreement and he's branded an outlaw.
12. He then learns that the Riverbank Massacre was a set-up orchestrated by the "shadow government" (for lack of a better word) that created the super-villains in order to get the heroes in their back pocket--Agent Hill was also in on the conspiracy--and guaranteeing that registration would get passed. However, they underestimated Captain America.
13. Peter ends up leading a group of heroes to save Cap or something, an all out battle ensues, but then it is realized that Baron Zemo is leading a coup attempt and it is stopped. But it's too late. A major character dies as a result.
14. Because of both of these things, there is distrust fostered among the heroes. Now there are two ways this could then go:
A. The Doctor Strange mindwipe scenario that I thought up here:

(And no this would NOT erase the events that transpired in Civil War like the Riverbank Massacre or registration, nor would it erase the memory that the general public DID once know Spider-Man's real identity.)
or B. Peter Parker goes into hiding to evade the authorities, a la Richard Kimble in the Fugative. Based on Joe Q's comments about "not using a mind-wipe ray" and exploring this new status quo for "a year and a-half," this seems like the most likely road they'll take before Marvel is forced to resort to option 1 once they realize that Spider-Man needs to go back to the "ordinary guy behind the mask trying to balance an ordinary life with his being a superhero" template. Especially when folks see Spider-Man 3 and Marvel tries to capitalize on it by making the comics fit the movie once again.
And all the while, long time readers, causal readers, new readers, and eventually even some Marvel Zombies will feel cheated and used, just like what happened during the Clone Saga.
