Hot-updating any package should not break any running VMs. If it does, it's
a bug.
I personally agree it's not the best habit to do it nevertheless, and I
expect users to put hosts to maintenance before performing any upgrade.

We cannot tell which update requires maintenance and which doesn't (or for
that matter - requires a reboot or a service restart) - there's no metadata
available to do attached to the packages that can tell us that.
