This is an ancient business model (https://www.ghostscript.com/ did that in the 80’ IIRC): delaying releases and selling access to them earlier. It did not work out significantly although there has been a few examples that persisted in implementing that strategy.
A platform designed to facilitate the implementation of this particular business model is a novel idea. But I’d be extremely surprised if it gets traction.
I think this should be a good fit for discussion on https://coding.social/
