Yup, you are right; my thinking was to prevent anyone getting ideas and diverging the "flavoured" variant in ways that breaks its core functionality as a `spirv64` target, but that might be needlessly defensive. If we don't feel there's much value here, I'll revert the test spam around core functionality.
