Well it could also be something like warning when Perfect Forward
Security is not available (for instance). However, as long as
gnutls-algorithm-priority keeps working I can live with that. :)

Well, DANE allows for storing certificate info in DNS and verifying its
integrity with DNSSEC. This has the nice property that no CA is needed,
and can give as good or stronger guarantees on cert integrity as
verifying against a CA can.
The downside is that it's not terribly widely deployed yet, and also
that it requires working DNSSEC support to work.

Tangentially related, one thing I would like to be able to have, is to
have multiple fingerprints stored for the same host,post tuple *at the
same time*. I run into this problem with servers that do round-robin to
different servers with different certs for the same hostname. I'd like
to be able to store all of them at once (by, for instance, connecting a
bunch of times and trusting the certificates one by one, and then know
that after that a mismatch should be considered suspicious).
