Which is why most distributions and other projects has moved to WKDs for key discovery. I don't think this is a good argument though as there are alternatives, even though they don't work super well at the moment.
Yeah, WKD is a first-class citizen in GnuPG. Creating signatures with "--sender $EMAIL" embeds e-mail in the signature and then gpg --auto-key-retrieve --verify will fetch the key via WKD without the need to touch keyservers.
