That way, we can decide how many stuff should be included when generating the various test combinations (and maybe just keep the main mode for standard executions).

I can look a bit more at this and separate the full configuration out into a separate test group perhaps, e.g. we'd have like `run-test-jdk_foreign` and `run-test-jdk_foreign-full` (or with the default reversed).

Isn't the additional parameter pretty much what we do now?
