Hi dpdev, and welcome to CI.
I quite agree with php_penguin: testing by ourselves is the best way to know. You could even look in the url_helper what exactly this function does. That's REALLY interesting to know the internals of our framework.
My answer is: this can be a proper way, but hooks will catch things faster, preventing the framework to load useless libs.
