The security issue in question is "HTTP request smuggling" which is an
attack vector which always takes the form of a malicious request from a
user-agent.  All it is the other way around, is a broken server putting
itself at risk.  There's no justification for a MUST even if there is
consensus for it.

I thought the consensus the WG was after, was whether or not to discard
all but the first C-L or the last C-L.  The current proposed language
says read to connection close, instead.  This makes loads of sense to
me, instead of MUST fail hard based on what concern, exactly?
