I was responding directly to your "related note" that you believed the 
spec was "unclear as to what the implementation should do when a valid 
IANA-registered vendor-specific constraint is provided to 
MediaStreamTrack.applyConstraints() that the implementation does not 
recognize or support".

So you were talking about constraints in IANA, *not* in section 12, so I 
don't see the relevance. I found your phrasing peculiar, because it 
doesn't affect the algorithm whether a vendor-specific constraint is 
IANA-registered or not.
