I've been using openssh-portable from ports with the none cipher patch
to get around this.

IIRC, upstream openssh refuses to merge the none cipher patches "because
you shouldn't do that". But I'd vote for having it compiled in and just
disabled by default.

It will refuse to let you have a shell without encryption, and prints a
big fat hairy warning when encryption is disabled.
