1) WKD should offer a key with a single UID.
2) Validity refers to UID's, not to complete certificates. Even if there
is some other UID on the certificate, TOFU would only validate the UID
that it has seen a mapping for.

You validate a relation between an e-mail address in a UID and a key. If
you change the e-mail address, there is no UID to validate, there is no
relation, nothing.



I use the GNU Privacy Guard (GnuPG) in combination with Enigmail.
You can send me encrypted mail if you want some privacy.
