the same key blob no matter who (or what) is making the request. Given this,
there is no real reason beyond tracking and statistics gathering to send a
user-agent string, so we don't, as it is really nobody's business what client
you are using.

Since all HKP requests are under /pks, I really don't see how an User-Agent
string would help differentiate them. Also the default port for HKP traffic is
11371, that alone should be enough for a proxy at the client end.

Easier than port 11371? There's only an issue if you're sending HKP traffic on

Keyserver requests from gpg are handled no differently than requests from PGP
or any other client. They are easily identified by being on port 11371 and/or
being under /pks.
