I thought the issue was "If we fix problem X of TCP (very slow to
start), should applications be able to test whether that fix has been
made, and disable their old work-arounds (opening multiple
connections) if it has?"

OK.  So, the client wants to issue small requests to some server and
expects content in return (a la HTTP).  How many connections should it
open?


RFC 2068 section 8.1:
   Clients that use persistent connections SHOULD limit the number of
   simultaneous connections that they maintain to a given server. A
   single-user client SHOULD maintain AT MOST 2 connections with any
   server or proxy.


The server controls the initial cwnd that matters and the client
controls the number of parallel connections.
