This prompted FreeBSD PR207679, and they were restored in r296634. It's time to retire this local change against upstream OpenSSH; the ciphers should still be available via a configuration option if anyone needs them but they should not be offered by default. Review D25833 is open for the change: https://reviews.freebsd.org/D25833
