You have summed up the use-cases rather well.  Thanks.

I'm afraid it's not that simple.  I don't think we need any radical
changes in Emacs to be turned on by default, but maybe something like a
set-up wizard or "New to Emacs? Click here" would be useful.

I'm not sure whether Emacs can reliably detect updates or not.  IIRC,
there was a discussion a while back that said no.  Plus, as I've
previously mentioned, I don't think Emacs should adopt any drastic
changes as the default configuration, but instead make the changes
easily discoverable.  (or at least until all of us old farts have had
another decade or 2 to adjust).
