Point taken. We can trim it back.

This is something we have been kicking around recently and were thinking to put it out to the group to get consensus on. We were thinking perhaps it is best to define one label for each usage of STUN (as was done in Section 4 of RFC 7350) that may use (D)TLS, i.e. stun.turn, stun.nat-discovery, stun.nat-behavior-discovery, etc).  This feels like the right level of granularity for the label. If folks think it is useful we can even throw in a wildcard label (stun.*) as a catch all implying whatever STUN usage.  

Thoughts?

We're happy to be agile and give it another quick pass. Thanks for the feedback.
