netstat does work, as it uses another interface to get its metrics.
I've been very careful to check that. Also, I've tested it under
-current where I'm using gated and didn't have to recompile it
either.
It doesn't seem to break route or ifconfig either.
A quick grep through /usr/src/*sbin shows no occurence of "struct
ifaddr".

It's purposely not in 3.2-RELEASE, I've been very careful to avoid
risking breaking the release.
I'd really prefer to back it out only if there is evidence of
serious problems with a given system utility.
