Stopping admins from shooting themselves in the foot by running a stupid
sequence of apt commands without understanding what they're doing, should
not be given higher precedence than ensuring that the vast majority of our
users are able to cleanly upgrade by following our standard upgrade
instructions.

So yes, it's a downside that this is possible when using the Replaces
without Breaks or Conflicts, but it's definitely a lesser evil.
