    No, the case is not handled correctly. If the shape is Unspecified, any finger position should be valid, the case should be handled with a "continue", not a "return false". This is even worse because the XR Hand Shape Editor now force to specify one or more conditions to every finger (and I think it's a poor idea), so the only work around, if you want a shape that does not use every fingers, is to provide a curve with a threshold of 1 for it to succeed...
