This is intriguing; i like it a lot. I think power a balance between maintainers and contributors is critical. Of course theres always ultimate option to fork but i think that should be an action of last resort if maintainers and contributors really cannot coordinate effectively.
In order to really study how this might affect the balance, I need to spend some time thinking on how exactly to incorporate it into my computational experimental apparatus, but i am pretty confident there would be a good way to pull this into the strategic game framing of decisions.
For reference, here is a drawing from the report was my first framing of the strategic variation of the users. Adding this in would be a 4th pink diamond and the second action profile for the contributors (rather than the maintainer which already has the cred release decision and parameter selection decision).
