> I wonder how much of Proton development is really Valve and how much is originally Wine contributors though.
Both! They gained the advantage of 20 years of work on Wine before they started distributing it. Now they're continuing to push Wine forward by funding further development. Most work on Proton is sent to upstream Wine first, and is then merged back into Proton. All of this is visible in the public repositories.
This is exactly how open source should work :) Valve's Linux team are good open source citizens, you can rest easy.
