Android Vector Resource Corner with elliptical arc

Question

<corners> inside <shape> tag is used to get rounded corners with circular arc in vector drawable in android like this :

<corners
    android:bottomRightRadius="16dp"
    android:bottomLeftRadius="16dp"
    />

But there does not seem to be an easy solution to get rounded corners with elliptical corners. which is very easy to do in CSS like this :

border-radius: 5px/10px;

Is it really impossible to do so without custom <path> tag inside <vector> or there is easy solution I am not aware of?
