That was the goal under Mozilla. Now that they aren't paying for the work anymore, I would expect other employers (and volunteers) to want more out of it than a tech incubator for another project.
It seems like that may already be taking place as part of this launch. I downloaded it to try after asking this question and it mostly works. Just some aesthetic stuff. If I can read news and wikipedia I'm pretty happy with a browser. Maybe make everything beyond documents a PWA or app?
Yeah, I'll admit my info/perception is out of date but I guess because after they split from Mozilla I mostly stopped following any updates. Maybe I'll play around with it this weekend just to see what it's like.
