Lack of interest Add Jabber to the messengers in “Contact Details”

One thing I'd really love to have is a Jabber profile field. I get it, there's Google Talk, and that's pretty much XMPP too (and I can just add my Jabber ID there if I want to), but I'd find a separate field for “Jabber” even more convenient because it's not actually the same—and Jabber being my primary messenger I kinda miss it.

I do miss that in vBulletin, too, by the way. Why are there almost no BBS out there who actually do natively support that?
