Question

Is it a good idea to use an extension method on the Object class?

This is an old question but I don't see any answers here that try to reuse the existing find function for objects that are active. Here's a succinct extension method with an optional overload for finding inactive objects.

using System.Linq;

namespace UnityEngine {

public static class GameObjectExtensionMethods {

    public static GameObject Find(this GameObject gameObject, string name, 
        bool inactive = false) {

       if (inactive)
          return Resources.FindObjectsOfTypeAll().Where(
             a => a.name == name).FirstOrDefault();
       else
           return GameObject.Find(name);
    }
  }
}

If you use this function within the Update method you might consider changing the LINQ statement with an array for loop traversal to eliminate garbage generation.
