So, you are saying that applications built on FreeBSD 7 or earlier
that use RTF_LLINFO will no longer work properly on FreeBSD 8 after
your change?

Ignoring everything else, that would be a killer and the one reason
to definitely change the current situation.  Otherwise, ISVs will need
two builds, one for FreeBSD 7 and earlier and one for FreeBSD 8, and
believe me, that is bad, bad, bad.  Or rather: unlikely.  (GNU/Linux
distributions do provide this level of compatibility.)

Sounds like that is the case?

emulators/wine still is broken, and upstream Wine has not accepted
the patch yet.  I believe one reason likely is the above, and the
fact that this may break commercial builds of Wine.

How are you going to address this?
