One niche Godot (or any OSS game engine) can't fulfill is seamless console ports.
In the long term, if Godot gets big enough then console makers have incentive to assist in this themselves, because if an engine with major marketshare can seamlessly port its games to Xbox but has difficulty porting to Playstation then Xbox will have a competitive advantage.
In such a scenario I don't think the difference between Godot and Godot* matters that much, IMO - I could imagine an Xbox devkit shipping with a Godot* compiler, for instance, so devs don't even have to think about the issue.
