I don't think we want this to be RefCountedGarbageCollected, that will cause the
wrong type of reference counting to be used. This is not RefCounted currently,
and we shouldn't make it RefCounted this way. It is using ref counting but
manages itself. You need to go back to NoBaseWillBeGarbageCollectedFinalized
here.

Done.
