It is also important to note that testing with SELinux enabled but no
policy loaded is not going to be very helpful (last we talked that is
what syzbot is/was doing).  While syzbot did uncover some issues
relating to the enabled-no-policy case, those are much less
interesting and less relevant than the loaded-policy case.
