If I were a Marvel writer, I would introduce the concept. Not definitively answer it, just lay the seeds in case a future writer wants to go in that direction.
Maybe just make a psychological story where Wanda wonders what's real and what's not and, if altering reality makes the new reality "not real." They could focus the exploration more on her kids than anything else, but have someone question the Magneto thing as well (before it gets dropped).

That's not the Marvel way and, no matter what, I have to account for the possibility that some people actually liked the events (although God knows why - I didn't hate AXIS but Original Sin possibly pissed me off more than any other event, probably because it started with enough potential to give me hope). But Marvel is fine with retconning details, but they generally don't retcon entire stories and, for AXIS, there's no reason to retcon it. Let's leave aside Wanda for a second, everything else will just naturally revert over time without any kind of retcon at all.
With Original Sin, the only thing worth retconning might be the Man on the Wall stuff. But I'd probably let it go too. I do like that Marvel characters own their past mistakes most of the time. Pietro did some terrible things in Son of M in order to save his people (or those he thought were his people). In Mighty Avengers, they had the option to sweep it under the carpet and say he was a Skrull and they refused to take the easy way out. I think they might eventually bring back Nick Fury Sr. (in 10-15 years), but I'd rather not pretend the past didn't happen.

Some mutants literally died when Wanda depowered them so no the logic doesn't hold. If her spell had simply prevented future mutants from being born then it'd be semi-comparable, although halting evolution on Earth still would've eventually sent the Phoenix on a crash course towards it.
I thought Steve had admitted at the end of AvX that Phoenix had not come to destroy Earth just Cyclops in his opinion although it was Stark and the Avengers responsible for it.
Either way you did not know Phoenix is coming back according to Jean Solo Ressurection? Someone should warn the Avengers and start another AvX hahaha.
My God wonder how people might think that lives are less important than powers or that the victims should move when someone throws a toxic substance into the atmosphere or into the water instead of blaming the people who created the mess.
What kind of message is this.
Actually no, canonically and according to the Avengers; it didnt mattered that the it was the way to save the mutants, the Phoenix was a danger to all non-mutant life on the planet, and had to be destroyed. But i guess that this mess with the cloud is one those things that are wrong when the X-men do it.
Besides, it was the Avengers' fault that evrything went downhill and out of control in AvX.
