Just for the record, dpkg-divert is not just for local admins.

But is update-alternatives really an alternative here?  It can only be
used by cooperating packages, where all of them agree to use
update-alternatives.  If the package with the file in question do not
use update-alternatives, none of the other packages can use it either.
While dpkg-divert can be used by non-cooperating packages.

How is the Debian artwork packages picking gdm3 background?  Can't we
use the same mechanism?
