I don't know about *strictly* better. Two connection pools is an 
increase in complexity in the LB and could lead to worse performance. 
You might have to pay a penalty of opening a new connection to a server 
even though you have a connection ready, whereas in HTTP/1 you didn't 
have to open another connection. Are we really so pressed for bits in 
the flags that we can't move this there? Maybe SETTINGS is not the right 
place for enabling/disabling server push.
