I'll take a crack at it in the morning (we all seem to be on borrowed
time this week).

Perhaps the cover announcement should impart the initial spin as a
request for the community to create, explore, and learn from use cases.
That will help make the discussion more constructive, less abstract, and
more grounded in reality (wishful thinking).

That probably beats, "Here's 3500 words of proposal; do you like it?".
