Nope. Faceid seems like a step back from touchID on the iPad since it only supports one user, whereas with touchID you could have multiple finger prints from multiple people. iPads are more likely to be shared than iPhones.
I don’t feel like this is a factor. You can have two faces and five finger prints. I would imagine most people use more than one fingerprint per person. I use four, thumb and index finger on each hand.
