It would be useful if you would please quantify "quite a bit" and for 
transparency reasons to please provide a Publicly available reference to 
this "feedback".

The proposed change would require the spec going back to LC. Is that 
correct?

The proposed change, plus new test case(s) for the new feature, would 
also result in the 4 implementations that now pass 100% of the test 
suite, would no longer comply to the test suite until those 
implementations are updated:

Is that correct?
