Hey, a client running in a web browser is still a client. You should also probably realize the point of using XMPP is that it's an open standard, and anyone is allowed to make their own implementation; contrast with the uneasy interoperability of, say, MSN Messenger with Pidgin. Now they're using Jingle, do you need a first-party client? You don't expect first-party SSH clients from your hosting provider, or first-party email clients from your ISP. And god knows there are enough IM/VoIP clients out there, so I'm all for thinning the herd...
