Comment:

 I believe that the current error levels for deprecated calls, wrongdoings,
 etc is intentional. Note that the default error level used by
 `error_log()` is `E_NOTICE`.

 We can't upgrade anything to an `E_WARNING` because they can become
 visible on the front end of a poorly configured server (eg one that has
 `WP_DEBUG` correctly set to false but which has `display_errors` enabled,
 and it'll also cause logs to fill up if they're configured to only log
 warnings.

 If we downgrade the `E_NOTICE` triggered by deprecated calls to
 `E_DEPRECATED`, I'm wary of this change causing deprecated usage to go
 unnoticed when a server is configured to log notices but not deprecated
 notices. Is this a common configuration?
