Are you referring to forwarded traffic? If so, how is that "protecting 
the router"?

If you're talking about traffic addressed to the router itself, the 
entire chain has to be parsed anyway.

That "ivory tower" is all we have documented requirements for. If you 
want to propose other requirements for routers, please do. But until 
then I do not support changes to standards to support non-existent 
requirements.
