I think that combining the GLs for profiles, modules and levels would be a 
huge mistake.  They were separated, as you said, to make it clearer.

Profiles, modules and levels are separate, but related concepts.  What 
we're missing is a better explanation for when to use each one.  In fact, 
we don't conform to SpecGL (Guideline 8.1) because we don't include a 
rationale for these items, especially modules.  We should concentrate on 
providing clear rationales, not combining them and making the water much 
more murky.
