My apologies, I assumed that the answers to those questions were 
self-evident in the edits made to the spec recently.

The purpose of those flags is to define conformance for HTML.

Relations can be updated to define how they work with HTML by using the 
process described in the Web Linking spec.

An example of a relation that we would not want to allow is rel=stylesheet 
on <area>, which we would want to disallow because it has no effect and 
is therefore likely an authoring mistake. Similarly, we wouldn't want 
rel=noreferrer to be allowed on <link> because it's not a link relation, 
it's a link annotation, and <link> doesn't create hyperlinks without a 
relation that creates one. Each keyword would have to be taken on a case- 
by-case basis.

Regarding the final parenthetical, I believe the templates fit what is 
described in the Web Linking spec.

HTH,
