Been reading the spec a bit more and I think this sort of also applies for static fields. They pretty much use the same mechanisms to be defined, only difference being the target object and when you initialize things (late in ClassDefinitionEvaluation for static, [[Constructor]]/SuperCall for instance). So again it seems we could try to change the createProperty stuff enough to accommodate these cases and it would cover both instance and static.
