I disagree that they are not the same thing for obsolete features.

It is pointless to provide semantics of elements (or other features) that 
are obsolete other than the semantics that form the element's (or the 
feature's) normative user-agent conformance criteria, since the only 
effect of such semantics is in deciding whether the element (or feature) 
is being used correctly, and obsolete elements (and features) can never be 
used correctly, since they are obsolete and must never be used at all.
