Will ARKit 3 support the iPhone 11's slow motion front camera within an ARFaceTrackingConfiguration?

Hello, I plugged in a friends iPhone 11 to see if ARKit supports the 120fps front camera when using an ARFaceTrackingConfiguration and the highest available AVFrameRate I could find was 60fps. Does anybody know if they will add the capability to use the ARFaceTrackingConfiguration at 120fps? Any help would be appreciated.
