It is. However, to use Transferable objects for purpose of implementing asynchronous parse/stringify, one needs conversions of JSON objects from/to Transferable objects. As it turns out, these conversions are just variants on JSON parse/stringify, so we have not simplified the issue.
Note that I would be quite satisfied with an efficient, asynchronous, implementation of these [de]serializations of JSON from/to Transferable objects.
