   I dont see a good justification for this change - the cost of reestablishing a connection is low (in scenarios where it is nontrivial, the network is unreliable enough that you want to close connections for resiliency).
   You can always bump up the timeout if you want to keep it around for longer.
   
   Unless there is a good enough reason for this change, I am not in favor of making it.
