The original reason was that there was a one to one relationship between 
a keepalive connection on the browser and a keepalive to the backend. A 
subrequest could not be serviced by a backend keepalive, as that backend 
could potentially have been in a proxied request already.

Proxy in 2.1 now has a connection pool, and my understanding is that 
this restriction has fallen away - subrequests should take advantage of 
the connection pool just like normal requests can.
