I mean it more as a counterpoint to what Valve is doing: games are automatically opted-in to working with Proton and pass through a Valve-operated certification program. Because developers aren't part of that loop, you see occasional cases where games issue updates that break compatibility, with users blaming developers based on an outdated, Valve-provided certification.
