Does this happen now even with merge tools for which we do trust the
exit code? If so, my original concern is addressed.

We're asking to user to signal that he's happy to launch the mergetool
and implicitly giving him an opportunity to break out of the session.
I don't see anything wrong with having this behaviour.

So long as we don't hit the loop-with-lots-of-error-trace for users who
haven't set mergetool.prompt I've no strong objections to changing the
default so long as an explictly set mergetool.prompt is respected.

Ideally, I think I'd like the prompt to accept a "launch/skip/abort"
range of options but that's a wider scoped thing. Sometimes when I'm
resolving a lot of things and not specifying any paths I come across
something that know I don't want to attempt a resolve with my currently
configured tool and I just want to skip it for now. Currently, I have to
either abort the session or let the mergetool fire up and close it again
neither of which are optimal.
