I leave my Steam update settings to only update on Play. This allows me to pretty easily review what is being patched in to any particular game and choose if/when to apply it (true that choosing not to apply means no longer using the Steam client for that game).
It’s also trivial on Linux to keep the Proton prefixes and game installs backed up automatically. This has the added benefit of making all game installs portable.
Unfortunately GOG still has no official Linux client, though there are workarounds. The “apocalyptic scenario” would ultimately kill either company, so you’re right to think it is moot.
