What BC break are you talking about? There is no need for using the parameter in old codes. Even if we pass that depth to jsonSerialize doing something like: "public function jsonSerialize() {...}" will still work without any problems. And how would you document it it? Like any other.. if there now is: http://php.net/manual/en/jsonserializable.jsonserialize.php abstract public mixed JsonSerializable::jsonSerialize ( void ) This function has no parameters. Then it would just be: abstract public mixed JsonSerializable::jsonSerialize ( [integer $depth] ) Parameters: depth Depth of the current json_encode -call. New interface would also be good, but as you said it, it doesn't seem to be worth the trouble. Well, and what do you think how much does going pre-processing slow the code versus without need for pre-processing? That really doesn't sound option to me.
