Considering if he actually contributed anything to Godot and this hasn't been another case of "look mommy, look what I did on the internet. I'm special mommy" as is typical with these kinds of people - as much testing as Stencilbits claims to do with this game, then Godot would have to be dumb as hell to allow anything from this guy.
I'd suspect they'd want to have some semblence of quality, and not be tied up for years on end retesting all the illegible garbage Stencilbits produces.
It's taken him 4 years (and counting) and not even there yet to do one thing with this game, so yeah I'm calling BS that he even contributed anything to Godot. Likely he is trying to leech off it and stay relevant while not actually doing anything.
