Please point to the text that requires *any* kind of interoperability
being demonstrated by running code. "successful operational experience"
does not state or imply interoperation between independent implementations.

This is a big change in principle from 2026, which is not what is advertised
on the box as "primarily a reduction from three IETF standards track
maturity levels to two."

I want a two stage process, but I don't want to lose interoperability as
an explicit criterion. To me, that's always been the meaning of the
"running code" slogan.
