A lot of the MUST in HNCP are not about interoperability, they are about
mandating the features that we want Homenet routers that we have.  In
other words, HNCP does not distinguish between "MUST or else you won't
interoperate" and "MUST because we are Homenet and we tell you so".

That's very well put, and exactly what I'm trying to explain to the
community.  Please help me do that rather than adding to the perception
that HNCP contains dozens of random, arbitrary requirements.

> There is a reason why the IETF seems slow.

You're changing the subject, Ted.  Nobody mentioned timeliness.

I'm arguing against making strong requirements that will be ignored by any
sensible implementer.  "Hey, you don't need to deploy that, but you still
MUST carry the dead code in your implementation".

How much more silly can one get?
