+1 to a small set of representative use cases to show that the proposed
architecture is not detached from reality.

-1. Note that having a few selected examples here doesn't preclude
keeping your nice and exhaustive "use cases" document alive.  I trust
the IETF datatracker for long-term archival.

My personal preference:
  * Not too many -- 4-ish should be enough, I guess;
  * Existing / deployed rather than speculative.

Cheers, thanks!
