Notmuch support for GnuPG Web Key Directory

[Ralph Seichter]

You may have followed a recent discussion on the GnuPG mailing list
regarding poisoned keys on SKS key servers, and possible alternatives.

I have set up a Web Key Directory (see https://wiki.gnupg.org/WKD),
which is easy to do, and now I am wondering about Notmuch support for
WKD. Has anybody considered this, and perhaps even compiled a list of
necessary steps to implement it?
