The conformance requirement is that the implementation can correctly
decode the test vectors as stated It doesn't require the codec to correctly

The discussion here is not related to modified or incompatible versions of Opus, 
but about things specifically described in the draft.

Perhaps you'd like to reconsider your statement?
