defer_transports is implemented by the queue manager. This is a
persistent process. It will not restart voluntarily.

Last time I looked, hold is not a message delivery transport.
You may be surprised to learn that defer_transports is implemented
by sending mail to the retry(8) delivery agent (Postfix 2.4 and
later). If you specify retry: in a transport map then it will have
the same effect.
This also means that the defer_transports feature is now redundant.
