Agreed. It's not clear to me you'd always want to use the same object though. E.g. for the simple case of Web Sockets no length is known and therefore it might be more interesting to get information about how many characters have been received so far rather than bytes. Though maybe this is too much complexity for little benefit.

Maybe just define a concept e.g. "message length" and for HTTP you define it to be the entity body of the request/response and for other protocols you leave it until when we get there.
