I'm sure the usual things like bagnon, gathering trackers and ui modification addons will be a thing like always, but I'd be shocked if they allowed the more egregious ones that essentially play the game for you.
Whine about "but muh 'nilla experience" all you want, but add-ons are third party and have no obligation to keep them functional, and they removed those ones because they didn't want the game on literal autopilot.
