Question: Why is E_USER_DEPRECATED used in stead of E_DEPRECATED?

[Rud5G]

In my production php.ini the error_reporting settings are:

; Default Value: E_ALL & ~E_NOTICE & ~E_STRICT & ~E_DEPRECATED
; Development Value: E_ALL
; Production Value: E_ALL & ~E_DEPRECATED & ~E_STRICT
; http://php.net/error-reporting
error_reporting = E_ALL & ~E_DEPRECATED & ~E_STRICT

This does not filter the E_USER_DEPRECATED triggered in https://github.com/zendframework/zend-mvc/blob/master/src/Service/ServiceManagerConfig.php#L127

Maybe i should have added this to #88

Because E_DEPRECATED can only be triggered by PHP itself, to indicate deprecated functionality in the PHP engine itself. For userland code (including frameworks and libraries!) to trigger deprecation notices, you must use E_USER_DEPRECATED.

BTW, you can add that to the error_reporting mask, too:

error_reporting = E_ALL & ~E_DEPRECATED & ~E_STRICT & ~E_USER_DEPRECATED

Thanks!, just wanted to be sure.
