Feature Request Animatorcontroller has a parameter?

I found this:

https://answers.unity.com/questions/571414/is-there-a-way-to-check-if-an-animatorcontroller-h.html

Code (CSharp):

1. public static bool HasParameter(string paramName, Animator animator)
2. {
3.     foreach (AnimatorControllerParameter param in animator.parameters)
4.     {
5.        if (param.name == paramName)
6.           return true;
7.     }
8.     return false;
9. }

It works but it would be nice to have something buildin for this.
