Whether any given feature is mandatory-to-negotiate or voluntary-to-negotiate. 2. Whether to define a generalized mechanism for such signalling, which would apply to all features. The mailing list post you've cited applies to #2. Section 2.6.1 of 3921bis applies to #1. I see your point about the <unsupported-feature/> stream error: it might not make much sense to define such an error condition if there is no generalized mechanism for signalling that any given feature is mandatory-to-negotiate...
