Hi all,

(cross-posting on openpgp and messaging mls)

during my work on bringing OpenPGP to K-9 Mail, I found myself
reevaluating a lot of things. This time it's about signed-only mails.

In short, my conclusion so far is that signed-only mails are very rarely
useful, they are holding OpenPGP back as a solution for encrypted
e-mail, and in the interest of usability we should not roll them out in
email crypto solutions on equal terms with encryption.

In some more detail:

I received positive as well as negative feedback about this, and I'd
love to hear more thoughts about it.
