I thought that was the reason you wanted to put the opaque stuff in the body.

The reason I'm pushing back is that it is possible to spend error code
bits on any amount of subdivision of the PROTOCOL_ERROR space.  Do you
want one for the case where someone didn't echo the bytes of a PING?
Or when they decide to send something else rather than continuing a
HEADERS block?  Or any of the many current and future
your-implementation-is-broken cases?  Ultimately, this just leads to a
blowout in error codes, to no good end.
