Comment (by gansbrest):

 Agree with all of you that disabling `error_reporting` is definitely not
 the most common practice, but I've seen more than a few cases where it's
 in fact disabled.

 In addition to that it's actually pretty convenient way to precisely
 control `error_reporting` via `ini` config in one place vs chasing
 `error_reporting` declarations across different modules.

 Personally I don't see a harm if we add couple additional
 `function_exists` checks in the core, since we already did it for the `wp-
 load.php`, but open to other suggestions.
