I don't see how this follows.  If n-m has been newly installed and is in
proper working order, and it sees that there's a trivially-configured
network interface in /e/n/i that it can take over, and it does so, how does
networking break?

And if it breaks, shouldn't we consider that a release critical bug in NM in
its own right, to be fixed for wheezy, regardless of whether NM is being
pulled in by default on upgrade?
