Just to be clear, are you suggesting evolving an extension without an evolution

Yes, not MUST NOT and not NOT RECOMMENDED.

But RECOMMEND using versioning extension and MUST assure clients do not break, 
whatever it means if not yet enough specified in STD 95.

[JS] To your "assure clients do not break, whatever it means” point, would it 
help to clarify that in the draft?

 From a client’s perspective, changes injected into an existing extension 
(without a successor extension) could fall into:

Breaking: new object class, referral with different semantics from another 
extension, altered JSON member value syntax, new required JSON member, new 
required query parameter
Non-breaking: new JSON member, new query path, new query parameter, new HTTP 
header

Does this change categorization look reasonable?
