Unity! Why isnt Unity exposing physx articulation joints?

Hi, i have been doing simulators for over 10 years, and have been quite happy with the different game physics engine out there.. started with newton, littlebit bullet, and most the physx.. In the last couple of years the rope physics has just gotten worse and worse, in Unity and physx.. physx has come up with a special joint called "articulation joints" it is more expensive than normal joints, but is also far more presise..
Please Unity, expose these physx joints to Unity so we can make some serious simulations..

 

I would really like a built in rope component. Does anyone know why it seems as though a lot of Physx features never come to Unity?
