Thanks. I don't understand why it makes no sense, but
I'll take your word for it. But I can think of a reason
to look up the key by email address even though you
have the keyid from the signature: when the key is not
on a keyserver or a WKD server, but is in a DNS
OPENPGPKEY record (DANE). But perhaps that's not a thing.

Thanks, but the manpage doesn't include DANE as one of
the lookup methods for that option. That's what I was
Since this option does a WKD lookup if wkd is in the
auto-key-locate list (and --disable-signer-uid isn't
used), it seems that it would make sense to do a DANE
lookup if dane is in the auto-key-locate list (and
--disable-signer-uid isn't used).
