Definitely.

Deciding on policies for handling opportunistic STARTTLS upgrades
combined with certificate failures has to be decided on, too.

That is, even if the user hasn't requested a TLS connection, Emacs will
auto-negotiate a STARTTLS connection now for virtually all protocol
types now.  If that "fails" because the certificate is self-signed or
expired, do we then want to bother the user by prompting for an action?
The user hasn't requested encryption and validation, but then this
question comes out of the blue?

So, er, someone (ahem) has to go through all the permutations of
connection types and failure modes, and write up some stuff.  We should
also have certificate management code in there somewhere so that the
user may be alerted if a privately signed certificate changes,
perhaps...
