Clarifying:

I still haven't heard from anyone that this solves a general problem 
that is widespread. The only actual example has always been CLDR, and 
its decision to ship these code points in XML. Shipping these code 
points in files was pretty far down the list of "what not to do" when 
they were originally adopted. My view continues to be that this is was a 
questionable design decision by CLDR, given what was on the record. The 
reaction of several outside implementers during this discussion makes 
clear that viewing that design as problematic is not just my personal view.

Usually, if there's a discrepancy between an implementation and Unicode, 
the reaction is not to retract conformance language. I think arriving at 
this decision was easier for the UTC, because CLDR is not a random, 
unrelated implementation. And, as in any group, it's perhaps easier to 
not be as keenly aware of the impact on external implementations.

So, I'd like to clarify, that this is the sense in which I meant 
"special favor", and which therefore is not the most felicitous 
expression to describe what I had in mind.
