Nope, Ted's comments in Paris were discussed at length when the editors
met in Palo Alto. The reason for the above rule (which I didn't know
when I was in Paris) is that it allows a resource-constrained client,
such as a palmtop viewer, to always limit its requests even when it has
no idea how large the response will be. Thus, it allows the client
to cleanly request only what it knows it can handle, and therefore may
reduce unnecessary network transfer and/or broken connections.
In other words, its a feature. :)
