As down as I am on the sequels, I never thought for a second they'd de-canonize it. The best I, or anyone who is down on it, can hope for is that they clone wars it. Mando has seemed to be trying to, and hopefully the movie will help. At this point though, it's probably just best to leave a sleeping dog lie and move to 200yrs ahead, or go complete old republic.
I'm sure the Acolyte story will finish up as part of the High Republic books.
Remember when SW "fans" were calling for the de-canonization of the sequel trilogy, and Pro and Doomcork and gang were constantly fielding rumors that a de-canonization was coming (along with KK being fired), according to their sources?
Filoni single-handedly cemented the canonicity of the sequels with every SW D+ series. Especially filling in the gap of "somehow Palpatine returned."
So, I'm with you. De-canonization is off the table.
