Seems like it is likely HM API's fault for modifying the return value to an incompatible subclass, though Polymer is also doing an unchecked cast here.
They shouldn't be wrapping the payload codec here, instead implement things with mixins.
Polymer's implementation is similar (as in functionally the same) to one provided by fabric api.
