I think it would be preferable for every package which wants to write to the
resolv.conf file to be required to use the resolvconf package to do so
(which is what I, and I think some other people, thought the situation was
until we read this thread). Uninstalling the resolvconf package would then
mean nothing could write to the resolv.conf file.

I've been in the fortunate position that I've never needed to install the
resolvconf package and nothing has ever tried to modify my resolv.conf file.
I've obviously led a sheltered life.
