The issue is not the powers, but that people want them to directly to come from Carol.
		
		
	 
I won't try to convince you of anything, but I don't think it's fair to call it trivial or "just how Rogue gets her powers".
If there's any essence they should capture is that Rogue has a tragic origin story.
And one of the reasons why (I assume) you maybe don't want it, it's why it works (imo): Carol 
is a beloved character. It should be tragic, sad, dramatic and impactful to work. And that's one of the stuff Disney/Marvel is missing too: balls for dramatic stakes.
This story adds a tragic layer and has a big emotional impact on both Carol and Rogue. It adds a lawyer of abuse between Rogue and Raven. It adds that distrust layer between Rogue and the X-Men. It adds another layer of trauma for Rogue, between other things.
It's true that The Marvels flopped, Larson has been harassed on social media and we don't know how long we'll have Carol in the MCU. Not to mention she has different powers too.
But regardless if they'll adapt that story or not, the essence they should keep is giving Rogue that tragic, traumatic, dramatic and impactful origin story. And I don't think replacing Carol by Gladiator for instance would necessarily work because, again, it's not just about the powers.
Oh and just for the record, Carol doesn't have to be in coma or depowered for it to work.
Anyway, lets hope they make the best decision.
