Hooks do have the danger that package maintainers will use them,
altering the behavior of standard tools, which will send local admins
working on autopilot, hung over or tired down the wrong alley.
Actually, I don't quite see why ucf would need hooks since it is
called from the maintainer scripts, giving the local admin full power
of creativity anyway. Chances are that ucf is already the right tool
to maintain systemd and friends the Debian way if the Debian packaging
team would be willing to.
Regarding dpkg, its conffile handling is IMO beyond repair, it should
be deprecated and later removed.
