With to #4 in that message, Blob/File/FileList are readonly, so there is no writing to the same object. Given that workers and indexed DB depend on this feature it is not going away. We could rebrand it as marshalling as suggested in that thread I suppose, but I was mostly interested if this was something we should be able to express in JavaScript as well. There's also a concept of transferable objects for objects to which you can write, such as ArrayBuffer.
