I was chief architect of Mozilla back in the 1998 October roadmap period and onward, when we created XUL. Indeed we wanted powerful extensions, and got them. Problem is they tied Mozilla down for too long, without anyone stepping up to find a way forward that didn't just seem to signal "XUL going away... <angry dev feedback>. Oh never mind; or maybe later".
Brave UX will evolve but slowly and without big changes that break too many users (Australis). Still, we need to be able to change our UX. So if we have powerful extension APIs into that UX, we can't promise never to break extensions that use those APIs in ways that become unsupportable.
All we can do is try to co-evolve nicely and cooperate better. I don't see a silver bullet here, but I do see how Mozilla has burned a lot of add-on developer good will -- and we won't make that mistake at Brave.
