cakephp: 3.0 - Define request query value if the result is null

Hello, I just have a convenience suggestion. Frequently we have to handle request queries. It often becomes a bother to check if the return value is null, and then define a default value for it with empty() or === null, or something like that. Symfony handles this really nicely by simply being able to pass a second parameter to the query function, as so:

$limit = $this->request->query('limit', 20);

This would essentially return 20 if limit was not given as a request query parameter, thereby making the code more readable, and programming faster. It also wouldn’t break code written in older versions, as if a second parameter is not given, it just returns null as it does now.
