IT has been recently removed from the diagnostics screen. I'm not sure when it will be needed to get back again on that screen. Probably keeping it is a lot easier than reimplementing it.
Sean Nash, Dara Navaei, Please create a case for UI when something like the HD/DG changes in the common repository which definitely impacts UI behavior, and sometimes stops UI build. It should be done when the actual code is changed in the common repo, not the dialin. I am going to update UI now but the comment is for later.
