Yes please! This is an "obvious" feature to those of us who are router
geeks, and I've been wishing for this to show up in FreeBSD for years.

Now if I could have "sticky" static routes also I would be even happier
(as in: Next hop disappears -> route disappears. Next hop available
again -> route shows up in routing table again).
