None.  It's just not useful from our side, but it does no harm either.

(In Debian world, there's no tight integration like you have by
putting FreeBSD kernel and compiler(s) in the same repository.  A
particular version of GCC can be used to compile for one kernel or
another, so we wouldn't be able to "commit" it to a specific kernel
version)
