That only applies if you are creating multiple PDO objects and expecting re-use of the kept-alive underlying connection, correct? If persistent connections were removed, it is true that any users utilizing PDO in this ad-hoc fashion and expecting connection keepalive would be impacted. Granted, that potential impact may not be tenable, but the workaround would seem rather straightforward to communicate to users and to implement - that workaround being for the user to introduce a PDO singleton to hold the object reference as long as you wish the connection to live for. >
