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?

What's the point? Why would anyone emit "stun" when something more precise is available?

We thought of it as a parent identifier, an umbrella label that identifies all STUN usages. But I agree, it doesn’t serve too much purpose for this label to identify usages that already have well defined labels.
