There is already such a tool available in the archive called
"needrestart". It does the mapping of processes to systemd services and
offers to restart those services after an upgrade (via a dpkg/apt hook).
So it already does exactly what I was describing.

This should solve exactly what you're looking for.

I've been running needrestart for a while now and really like it. You
should give it a try.

I agree with Marco, this is not something which needs to be solved on
the systemd package level.
