Well, having done this on four different machines in the last couple of
months I can say for sure that apt did NOT resolve this dependency and
left exim installed so I had no choice but to use force in removing it.
:-)  This may have been a bug in the Debian package dependencies or
something else, I'm not sure -- but either way I found it was necessary
in my case.  I wasn't aware of the "!package" so that's neat to combine
the two operations into one but otherwise I don't think there is
necessarily anything wrong with my approach.  Having said that, the use
of --force is fortunately pretty rare in Debian. :-)
