This was discussed and done on purpose -- put the most fundamental and 
important stuff up front, even if it overlapped stuff further into the 
body.  That in turn followed from refining your original outline into draft 

It is explained in SpecLite FPWD [1]:
"The scope of content in a good conformance clause overlaps most of the 
other remaining topics in these specification guidelines. Possible 
repetition notwithstanding, a handful of points -- conformance clause Good 
Practices -- are worth mentioning here up front."

I don't mind if we address and change that decision, but I'm concerned that 
we're not doing that explicitly, rather we're erasing it with a series of 
small editorial steps.
