You seem to be saying it's not legacy, and then saying that it should be
legacy? I'm confused because the documentation/enablement is so poor a
systems administrator can not currently use saned whether he is informed
or ill-informed about it's security implications.

If it has security problems, then just say it's disabled and can be
enabled thusly, report a bug upstream about it's crappness and how it
should use ssl, gpg etc. Otherwise we have a feature that sounds
dangerous (could blow up in your face) and is so difficult to set up
that setting it up looks like a big fat packaging bug.

Surely normal operation shouldn't look like a bug, regardless of how
carefully you want systems administrators to consider the security of
their system?
