Okay then, let's replace the reference to XEP-0045 by one to the new XEP.
The old XEP-0027 also has the following advantage against the proposed one:
since the key info in XEP-0027 is distributed by presence updates, all parties
interested in using OpenPGP automatically have this key info. In the proposed
XEP one has to explicitly ask every roster item and every MIX room member
to get his key (or to find out that there's no key).
Also, what to do if a user have some keys published and currently is logged
in using a client which knows nothing about OpenPGP (and posiibly nothing
about pubsub at all)? His contact can still get this published key and send
an encrypted message which will never be decrypted (and likely will never
be noticed because it has no body and no recognizable message subelement).
