1. The phrase "for the initial round" is explicitly stating that the goal is
near-term.  From one perspective, that is the very definition of short-sighted.
 In other words, that is exactly what I intended, although of course not with
the negative connotation of the latter term.

2. Statements about what works and doesn't work, for adoption of Internet
standards should come with some sort of empirical basis.  My own basis is that
every Internet protocol that has succeeded has begun with a modest list of
functions and has grown from there.  (Yes, I said every single one.)

3. A claim that we only ever get one or two versions of a protocol is
demonstrably false.  More importantly, it a) misses the model of incremental
extension that has been so successful for so many Internet protocols, and b)
seems to have a remarkably high correlation with the production of large,
complex, cumbersome protocols that get released late, never get fielded or never
work very well... (IMO)


Bottom Line:

     Although it is essential that a protocol specification be deployed only
after due deliberation, it is equally essential that it be concise, coherent and
compelling.

     In other words the market needs to understand it and needs to believe its
adoption is important... for the near term.

All of this argues strongly for the criterion I suggested.
