Complaints I find the most baffling. If we know you managed to screw up
your update once, why exactly would we just trust you to get it right
the *second* time without any testing?
* If the package is already so screwed that it breaks the whole system, it
cannot realistically get any worse.
* A regression fix is usually a trivial change, often reverting something to
a previous, already well-tested, state.
