All this code verifies that the thunk for the static runtime imports everything the dynamic runtime exports. Since the static runtime is gone there's no reason to check this anymore, it's always true because there's only the dynamic runtime.

I mean, theoretically we could include this after the commit that actually removes the static runtime. But since it's a pure testing change things will "work" even if we remove coverage for this now.
