This is simply not the case.  freebsd-update works on the basis of
cryptographic hashes on the binaries. It is, after all, a binary
update program.  If it detects a custom kernel, it will not update the
kernel, but updates userland programs.  It doesn't *care* what your
kernel config name is, it really doesn't matter.

Kernel update becomes a manual operation, which requires fetching
sources from the SECURITY branch.
