My experience with the WAI Guidelines suggests that conformance
to requirements that are as general and broad as those in
Webarch will not be as useful as conformance to domain-specific
requirements derived from Webarch. 

For instance, suppose I am a format designer. I would find it useful to
think about a statement such as "A resource owner SHOULD assign a URI 
to each resource that others will expect to refer to." I would
find the following more useful:

"If you are designing a format specification, assign a URI to the
 following components:

  [  ] Elements
  [  ] Attributes
  [  ] Functions
  [  ] Properties
  [  ] Values of properties or attributes
  [  ] Exceptions
  etc.

"If you are designing an API ..."
"If you are designing a Schema ..."

And so forth.
