I'm not suggesting that tunnels are forced to check what they forward, but that they assume responsibility for every byte they produce, forwarded or not.

An intermediary can forwards in the way you describe in that case.  But if the source produces junk, the intermediary can wear the consequences.  That doesn't mean that you have to check everything you get, but that's a call you would have to take on yourself.

The current text passes this cost on to clients in a way that will make it much harder to enforce protocol correctness at clients.  That's not healthy.
