Scopes are subsets of other scopes and are therefore allowed within eachother. Did you actually see misbehavior due to this issue, or see a real bonafide conformance test fail? If you're just reading the RFC and sticking tests here and there based upon what you read, without any testing or real life verification of the issue, this is _strongly_ discouraged. It would even be ok if you merely showed how another open source networking stack makes this test.
