I'm still not convinced by the use case for identifying "stun".

How else would normal Binding requests be identified? I mean, I don't have a use case, but as an implementer I need to know what ALPN label to use.

A comment for the authors: for each STUN usage you list, please refer to the corresponding RFC.

Sure.

At a minimum, remove: "(e.g., any labels starting with "stun.")"

The whole paragraph is hard to understand IMHO. I would rewrite simply: "stun: This label is used as a fallback for STUN usages that do not have a corresponding ALPN label."

Our intention was that 'stun' could identify any usage, including TURN/nat-discovery that have well defined labels, and not just a fallback for something that doesn’t have a well defined ALPN label. Too ambiguous?
