I _think_ I may be one of the people who complained at the time, and
if I recall correctly what Dave and I agreed about (maybe the only
thing) was that this was all a terrible mess that needed repair.  At
the time, I was still too much in thrall to data-theoretic approaches
to give in on Dave's pragmatic answer.  And I now see that Dave has
actually described better than I was ever able my objection:

I like this approach.
