Yup, I think that would be more flexible.

I think it would also be nice if the entire cert was also returned (in a
convenient format), so that Emacs can display the pertinent parts while
querying the user about what action to take.

Like "signed by CA foo on date baz for host zot" and so on.

And perhaps display graphically the fingerprint like ssh does?  I have
no idea what's involved there, so I don't know whether that would be
possible (or easy)...

Yup.  But perhaps Ted (or other people) have opinions here.  >"?
