nntp doesn't look like a issue, since nntp-open-connection-function is
passed through an internal association list to get the connection type.

As for nnimap, fair enough.  This can be solved by adding `network' as a
synonym to `try-starttls'.

Explaining the meanings of the :type makes the former scheme sound more
complicated: "try starttls if the :capability-command and :success and
:starttls-function parameters are present, otherwise open a normal
network stream".  As opposed to "try starttls".

But if you feel strongly about this, I won't insist; it's not an
important issue.  Should I bring the default back?

It would be cleaner to error out, IMO.  The :success and
:starttls-function parameters ought be checked also.
