I haven't done it yet, sorry.

Yes, that's intentional.  The mps(4) and mpr(4) drivers are also maintained
outside the tree by LSI/Avago.  I usually try to put version checks in
there, so that things work when they try to compile against earlier
releases.  Otherwise they'd be putting in the same checks themselves.  It
is easier to do them when the changes go in the tree.

camcontrol(8), on the other hand, is only maintained in the FreeBSD tree.
So it only ever needs to build against the FreeBSD branch it is in.
