I think this is on purpose; Roy has pointed out frequently that HTTP/1.1 
doesn't have an extension point for this.

Now, should we / can we fix this? Dunno.

In practice, new request/response headers are defined all the time, and 
people minting them just need to deal with the fact that conforming 
HTTP/1.1 implementations may treat them as entity headers.
