That policy does not doom anything. wlroots does not accept driver bug hacks for any driver, and is merely consistent in that regard. It works for others, so it can work for Nvidia. Things will just always move slow as long as Nvidia are the only ones that can fix bugs. Maybe it will be better one day: They are (also slowly) moving in the right direction though, and nouveau might be revived by taking some bits from their new (barebone) kernel driver. But until then, swear your allegiance to the GPU vendors that play nice.
