Well, the issue is what we do when we get a certificate we can't
validate.

The traditional thing to do is to query the user for whether to connect
anyway, and whether to record a permanent exception for that
certificate.

The code to do that hasn't been written yet.

It's very common for SMTP and IMAP servers to use self-signed
certificates, so just forcing ":validate t" for all connections would
essentially mean that Emacs would be unusable for reading/sending email
(using encryption) before that code has been written.
