Everything has to be read in context. My reading of this document is that it says what an implementation SHOULD do _iff_ a stable IID is to be generated. It says nothing about what to do if a stable IID is not required.

I find the current text quite clear on that, but clearly you don't.
Would it help with some sort of clearer applicability statement in this document? Can you propose text?

Cheers,
Ole
