I categorically reject that thinking. Encrypted connections are useful
even without authentication. Your argument ignores the real fact that
eavesdropping is easier than man-in-the-middle attacks. Even if there
weren't any significant difference, what is the gain from switching to
unencrypted in cases where we previously used encryption? There is
none.

And it still moves us to "less secure than 8.3 by default", because
configurations that formerly used encrypted connections might now use
unencrypted ones. It's not acceptable.
