There may be the case when you want/need to extend the `mysqli_stmt` class to add or overwrite some behaviour. In my case, I'm overwriting the `mysqli::prepare()` method to return an instance of my own class extended from `mysqli_stmt` to change its behaviour in some integration tests.

So please, do not remove or block the ability to use mysqli::__constructor(). Thanks!!
