If you do that, how do you ensure that these two cases are both handled

- after installing the coldplug package, the admin purges the hotplug
  package, and later reinstalls it (removing coldplug)
- after installing the coldplug package, the admin reinstalls hotplug
  (removing coldplug), expecting this to give a hotplug package with a
  working config

Since the principal reason for preserving these unmodified conffiles would
surely be so that they could be restored later, both scenarios seem
