I agree that JUST-THIS-ONE would be cleaner, but I disagree that it
would be more conservative.

I can't speak for Michael, but in my view, "conservative" is a measure
of the amplitude of the change.  The change that Michael and I are
proposing, despite being objectively ugly when compared to removing
JUST-THIS-ONE, is _less_ removed from the current Tramp mechanisms than
your idea.  Thus, it is safer.

I think this analysis is very interesting and valid.  Not necessarily
for fixing this particular bug. You should send it to
emacs-devel <at> gnu.org so it becomes more visible to people who may not be
following the bug tracker.
