I'm sure it is, but freebsd-update is a binary distribution system, and
doesn't build anything on the client.

I believe part of this issue is that if the kernel isn't distributed with
a patch, then it needs to be represented somehow. I've heard of some
thoughts focusing on reflecting the patch as a sysctl value.
