This isn't really a 'fork it' type of problem. Closest to that I can viably do is just have my project elsewhere (gitlab or codeberg, or even just uploaded to itch) and allow the bindings project to link to it. Even then, it could still be scraped one way or another.

I don't really understand enough to improve the bindings code itself and the project only currently has 4 other contributors (and those likely aren't anywhere close to half-as-much as the creator), so the idea that moving would harm said project definitely is valid.

Godot itself is large enough that it could survive a move, though it's likely too complicated with all existing things (unless they split out for ultra-future 5.X?). I do know that worse people (maybe-or-maybe-not better coders) have tried to fork Godot with the long-term outcome likely not being noteworthy.
