Difference between "Tangent" socket and "Anisotropic Rotation"?

I'm wondering what is the use of the "Tangent" socket at the bottom of the "Principled Shader" node if I can already rotate the orientation of the anisotropic effect with the "Anisotropic Rotation" value? Maybe some more complex distortion effects?
