It was my understanding that this was EXACTLY what dependancies were
designed for; Protecting the installer from removing functionality that
other packages need.

This is not a technical argument. It is an economic one, and should not be
listed as a primary point. (all change takes work) Your assertion that it
is needless is not yet backed up by technical arguments. In addition, the
modification of other editor packages to encorporate this new VPN are not
on any critical path, so they can happen as need arrises.

This is true for any package that has others that depend on it. If I want
to put a qmail of my own into /usr/local, I will still need to keep some
Debian mail-delivery-agent installed to satisfy other packages dependance
on an MDA. A way to tell dpkg about "non-package provides" would fix this
problem in general, but I don't necessarily think that it is needed, or

I personaly have no problem with this, as long as you can show a more
specific reason for doing so. So far I haven't seen an argument that is
"to the point".
