Oh, in email clients there is at least one thing to do in order to
support WKD: using gpg's "--sender" option with the sender's email
address when signing a message (if that email user ID is in sender's
key). The "--sender" option includes that email in the signature so WKD
lookup can use that. More information in gpg(1) manual page, especially
in options "--sender" and "--auto-key-retrieve".

I recently added Emacs's message-mode (and epg) that very feature. It's
in the development branch (master) since commit
emacs-26.1-6339-g74579d3d2b (2019-07-13).

Variable mml-secure-openpgp-sign-with-sender has to be non-nil.
