People are confusing testing with use. Those are two different kinds of
"interoperability", with the latter being far more stringent.

The new draft specifies the latter.  And it quite intentionally does not
specify the former.

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.

While "testing" is extremely important for when doing development, there
is no reason that the IETF should be required to include that very
intermediary activity within our standards process.

So the new proposal has two phases:

   1) Specification

   2) Use

That there are intermediate real-world phases, such as development,
testing and deployment is essential, of course.  But there is nothing
essential in having the IETF mark completion of any of those
intermediate phases.
