Well the game is in early access for 2 years. That's a long time. And yes, it is true that it was maybe inevitable. The pandemic slowed development down, and the scope of BG3 seems large, much larger than DOS2 for example.
However, there are some things i'd like to point out.
Although the game is in early access for 2 years, we don't even have the whole list of PHB classes and races yet, we don't even have access to heavy armor(plate) yet, and the biggest part of the game is not accessible. For all those things, we cannot offer feedback or see what bugs we might encounter. For a lot of things, we are at the same point, or almost at the same point. What kind of feedback can i offer more now? I can't test all builds, i don't know even if favorites like Hexblade will make it to the game, i haven't seen multiclass yet, i can't even properly test heavy armor str builds. Paladin, who could maybe fix that, is nowhere to be found for 2 years, although to be fair, putting divine smite maybe is more complicated than it seems without it functioning in a weird way. Still, it's not there.
So the whole argument of going into early access to provide feedback and help, still stands but, we can't give feedback on a lot of things. Things that when you see, the game will probably be feature complete.
Anyway, what i would like is, at least a patch that puts the 2 remaining classes and multiclass in, or at least a narrowing of the release window. Logic(?) says around March-April-May, but who knows.
A little more communication about what races and subclasses we will see in the final game would be appreciated. They have us in the dark, hoping our favorite subclass will make it, you can't convince me that they haven't decided yet what will be in the game and what won't at this point in development.
