By definition a test suite is about testing interoperability with the test suite. An HTTP test suite should likely test for whether response code 418 is implemented a particular way and while humorous it would still be an interop test no?

No, the git test suite is about testing the git codebase. If you want something like that, you need a conformance suite, which does not exist for git.
