WKD has some benefits over OPENPGPKEY - it keeps the request confidential (as WKD uses plain HTTPS). WKD is just easier to get right, that's why it's more broadly supported. GnuPG, that supports both of them, defaults to WKD. If OPENPGPKEY request is made it seems GnuPG doesn't even validate DNSSEC signatures: https://lists.gnupg.org/pipermail/gnupg-users/2011-December/...
