As far as I am aware, there is nothing intrinsically preventing people using it.
I have no experience in building big titles or even commercial games, but I see no obvious "blockers" to building a large and complex 3d game. It's not like Godot itself limits you to only doing basic 2d platformers or whatever - it seems as flexible and power as unity.
Sure you might not have all the same eye candy as the very latest unreal engine or whatever, so AAA quality titles might be out, and I am not sure what the multiplayer stack is like, but it seems like the fundamentals are there and so there is nothing to hold people back.
