Not only does this obfuscate coverage, but it also contradicts the requirements set forth by the RC documentation, itself. For example: "The conformance specifications must provide the mapping between tests and requirements to demonstrate traceability and coverage."
In addition, the lack of mapping creates confusion for RI development, since RI depends on both RA and RC. For example, if RC includes test cases not explicitly mapped to RA, then RI may spend time on test cases that are not actually required.
In order to meet the requirements documented in RC, I suggest that the RC work stream team create and publish a simple table that displays RA requirement references in one column, and corresponding test cases in another. This table should be updated for every release.
