I don't know if PGP did send the user-agent), and why not O.S. too, like we already use to stat with regular Web servers.

Not passing a user-agent is actually intentional behavior.  Unlike some sites which may want to behave differently for different user-agents, you get 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.

In fact, there is a TODO in the code to not pass the ASCII armor "Version" field either when sending keys to a keyserver.  I should implement that...
