OK, I should have qualified "they now have extra information about
you" with "potentially" or "access to."

The lower level of spam from publicising your email addresses on a
keyserver compared to web page suggests the first of these is true
(although that may be related to ease of extraction of email
addresses). I'm not sure how you would go about measuring the second.

I'm clear that this doesn't bother you.

Of course, but it doesn't have to be that way.
I do not see that users of openPGP gain anything at all from this
public exposure of their private details, if their key could be
usefully be made publicly available without.

Yes it is.

Well, you *could* include it in every email you send out; or use an
email auto-responder, post it on a web page, post it to BigLumber, etc
and use a signature notation (or a note in a comment line or an email
footer) to link to it. But most of these options probably fit the way
of working you describe less well than using a keyserver.
