So have Steinberg got around to making the metronome routable to an audio output so I can send the click into a headphone amp and have my artists determine their own level? Or do we still have to deal with makeshift solutions? 
You can do that for a long time already…
Care to explain how then?
Either via control room, or VST connections…
Neat-O! That’s what you get for not reading the manual.
Move along, nothing to see here.
