Yes, one time seems to work quite well for SSH.

Another, less automagic approach, could be to just place fingerprints in
some queue and allow a administrator to manually pin them.

That would be similar to like how some CA's who give out free certs with
the only requirement that you control the MX record of the domain.
And the XSF did have an intermediate CA a while back, but doesn't for
some reason that I don't remember now.
The thing I wanted to get at was to make it simpler for smaller
deployments, like some friends personal servers, to establish some
measurement of trust between themselves, without all the bureaucracy
that CA's brings.
