I disagree. If the framework is the only facilitator for communication, you
have a unique point of review and maintenance for the communication. If
policies can communicate freely, it's all much more messier.

Functions that provide plumbing between otherwise independent components
that live in total ignorance of each other are common in all designs, and a
sign of good quality in many.

My thoughts exactly.
