If you're serious about security, you shouldn't support LOGIN (or PLAIN)
unless adequate privacy protections are in place.  If you're serious
about standards, you won't support LOGIN.

Given that OpenSSL is in the base system, there is little reason not
to support BOTH StartTLS and SASL "out of the box".  I would suggest
the authentication defaults be relative secure, as in "noplain,noanonymous".
This will force use of StartTLS to allow use of PLAIN/LOGIN mechanisms.

I'd recommend bringing Cyrus-SASL into the base system eventually
under the same rational used to bring OpenSSL in.
