This goes to the essential challenge of a proposal like PSD.  It 
embodies a particular model, in the absence of clarity about the model 
or broad-based discussion of its appropriateness.  (Note, for example, 
that my review offered some discussion of that sort but got no comment 
on that discussion.)

In effect, it creates a strategic solution -- that is, a long-lived and 
embedded mechanism -- without a clear and broad understanding of the 
organizational space it is working in.

Forgive me, but while everyone involved in this has extensive experience 
and is trying to solve a real and serious issue, this is an 
astonishingly naive view.

The IETF does standards, not experiments.  Not /real/ experiments.  What 
it calls an experiment mostly serves as market testing, with a smidgen 
of engineering tuning later.  For the most part, IETF experiments 
produce an accepted/failed/needs-small-revisions range of results.  What 
it does /not/ produce is results along the lines of "that was 
interesting, now let's start fresh and do the real standard."

Perhaps there are exampls of IETF experiments that have permitted 
entirely starting over, but mostly those only happen when there is a 
complete failure, and those typically are called experiments.
