I think this is OK, but I'm not 100% sure about this one. This test file is used
to cover APIs that are not yet used in some parts of the compiler. I think the
test covers with code what we want to test, but I'm not sure if we also try to
keep things reachable as well.

Johnni - is it relevant for this test to keep this unused import?

No, this can be removed.
