BTW, the sub-addressing does not seem to be a real problem.  A cursory
inspection of some large keyrings showed that user-ids with
sub-addresses are quite rare and there is always the opportunity for the
user (or a tool) to create another user-id w/o the sub-address.  Thus
the sub-addresses can be handled in the MUA and won't need protocol
support.

I disagree but I don't think it is the time to discuss this now.  Let us
first deploy a useful key discovery and then see how it can be
improved/changed.

I concur.  Given that we need to drop the SRV records for silly reasons
anyway, we can also demand a fixed subdomain.  Given that I don't like
the "wkd" acronym, I would prefer to use a different name, like
"openpgpkey".

And regarding your other mail: Sure, a redirection can only be allowed
to use a http redirect and not with a CNAME.
