The only question I have is what’s gonna happen as game discs are just becoming an access token to download the game and its updates.

That’s a big concern. There’s communities trying to document which games are complete on the media and can be played from start to end without updates (so no major game-breaking bugs or huge performance issues) like this one:

I’m also part of a FB group that collects cartridge information for Switch games, to document if there’s revisions with all updates included.
