Not gonna happen, no matter how much some may wish it. What possible purpose could it serve to the franchise to basically ignore the sequel trilogy going forward, considering how much else they've tied into those movies? Does anyone actually expect them to make a new sequel trilogy or something else radical? And why would Disney invest considerable sums of money just to placate a vocal minority of fans who overreacted to what is and the end of the day a fantasy film? The sequel trilogy made a ton of money (yes, even Ep. 9), and the audience reception was not any worse than that of the prequels, and averaged maybe slightly better (obvious attempts at review bombing TLJ on RT notwithstanding). And The Mandalorian and the final season of The Clone Wars were successes, showing that the sequels didn't "kill" the franchise. The franchise is as popular and commercially viable as it's ever been. Disney has no real reason to do this.
Considering all the hate the prequels received 15-20 years ago (has it really been that long?), much of it the same in content and vehemence, it would not surprise me if there were people on online forums at the time hoping that Lucasfilm and Fox would decanonize the prequels. And if some fans did so, they clearly didn't get their wish. It's Star Wars. Nearly everything that wasn't part of the original versions of the original trilogy has been met with outrage (and there's probably still people that don't even particularly like Return of the Jedi). It's nothing new. Lucasfilm didn't completely overhaul the franchise in response to fan complaints in the past (even midichlorians are still canon), and they aren't going to do so now.
