Sure, but a lot of studios still maintain and upgrade bespoke game engines to ship projects.

All it would really take is a company of decent scale deciding they want to base their engine around Godot and having an appetite to upstream some meaningful work.

That's the part that probably won't happen, unfortunately. Not without specific contracting. Blind Squirrel (the devs behind the botched Sonic Colors remaster) didn't even credit Godot as an engine it based it's proprietary engine off of.
