There was a problem hiding this comment.
Observers normally have world access, but this signature doesn't expose it. Should this be either something like dyn Fn(&dyn PartialReflect, DeferredWorld), or a full impl IntoSystem<InRef<dyn PartialReflect>, (), M>? Changing it later would be a breaking change.
