That's not the point.  Patrick implied that adding the jumbo frame option kills the ability to efficiently mux.  That's simply false.

"Likewise, restricting packet sizes to a small length in order to prevent fools from HOL blocking
 their own multiplexed channels makes some sense, for browser developers.
 However, it actively harms applications of HTTP that are not interested in multiplexing
 because they only want to transmit a single large data stream.
 ... I don't think it makes sense to limit an application-level protocol to the worst case.

So let's be straight.  There are legitimate use cases for jumbo frames.  You and Patrick just think the world is full of a bunch of what Roy calls "fools" (see above) who will HOL block their own multiplexed channels.  Roy (and I) don't disagree.  Roy (and I) don't think it makes sense to limit the protocol to protect against an unknown number of fools.
