SET PERMANENT only works for those variables that can only have one
value for a given client protocol (for example datestyle in jdbc).
Whereas autocommit needs to be changeable by the jdbc driver since the
jdbc spec allows the user to call an API method to change the setting.

Reporting the change to the client seems sufficient for the client to
take whatever actions are necessary.
