It makes sense to include them in a dialog forming response. A normal 1xx is not dialog forming. My suspicion (though I didn't check if this was true) is that it went away when 100rel moved out of 3261. It can't hurt to send them, of course, but it would be ignored unless its reliable. -Jonathan R.
