Maybe a glimpse of him again at the very ending, but otherwise, I see the bulk of the film being about the side-quests and cosmic encounters Thor has while he tracks his vanished quarry. Encounters that may or may not include Enchantress and Skurge, Surtur, Fenris, Ymir, Malekith, Hela, Karnilla and the like.
That makes Thanos the main villain. You even say all the other villains are side
quests. That means they're not the main villain. If he does infiltrate the Treasury room, that
will be the side quest, a relatively minor plot point, like SHIELD in IM2, or in Thor, not the catalyst for the rest of the action in the movie. And doing so with a bad guy you're not going to get closure with... I don't see how that can be a good movie.
