I think we want our specs to be modular i.e. to separate concerns as  
much as possible and we should continue being careful to not build  
unnecessary/harmful dependencies. Based on what you say above, we  
appear to have met those goals for the P&C spec.

Indeed we have talked about creating some type of "uber" spec. I'm  
not convinced we need it, if all that it essentially says is  
something like "A widget user agent must implement [P&C],  
[APIs&Events], [DigSig], [...]". To me, such a statement feels a bit  
like what I would call a procurement statement (also know as a RFQ)  
e.g. "I'll only purchase an implementation of widget agent X if it  
implements specs A, B, C" and that feels like something for the  
market to decide rather than being codified in a spec.
