Just from vaguely reading their shorthand documentation (correct me if I'm wrong) but there doesn't seem to be a way to associate this with goals you've set for each event (you'd normally do this within your own code;) which imo means you're going to collect a lot of junk data you don't want.

I guess you could find out how it outputs the event and then set a goal for it, but I doubt it would be pretty and you're still going to get a lot of junk in your real-time view. I hate having to set-up callbacks for outbound links, it's a real pain in the butt (especially if you're having to instruct someone else to place the code,) and sometimes it doesn't fire properly on certain browsers so this would be nice...but it could also be messy (from my quick look.)

I do like that GTM can do -most- of this now, which allows the marketing/PPC/Analytics team(s) to do things on the fly without having to bother me.
