Good insight, Patrick. If I might suggest a point or two, it's that
there's more than one "expectation" here, or perhaps should be:

1. Expectation on protocol/policy behavior
2. Expectation on service delivery and economics

If breaking #1 doesn't break the basic functionality, but does achieve
something under #2, it's worth clarifying. If #1 doesn't improve #2,
there's a legitimate gripe.

Means and ends aren't always locked together.
