I don't feel very strongly about this, but I'm curious: Why don't you
want to obsolete at least some of them?  I think they add user
confusion and are just not very helpful.

Personally, I wouldn't mind a middle ground here: to only obsolete the
very low hanging fruit.  To be more concrete, it doesn't seem to me
that it would take much effort to immediately obsolete url-irc.el,
url-news.el, url-imap.el and url-ns.el.

I could volunteer to cook up a patch if that's indeed something we
want to do.  Otherwise, I suggest to close this bug report as wontfix.

Best regards,
Stefan Kangas
