I should follow up here to point out that pretty much all of the above
seems possible to do today, maybe with the exception of accepting the
use of persona certifications. It's probably not done more widely
a) doing this in an automated way is pretty clunky at the moment.
b) there's no common way to do it, which means that tools which share
the gpg keyring for e-mail don't have a common convention on how to
collaborate in such a TOFU scheme.
embedding these features to gpg itself would address these two caveats
somewhat, and could make for a more usable (and portable) mechanism.
