Star Alliance Gold Plus

The majority of Star Alliance frequent flyer programs (FFPs), including all the main ones, have more than one elite status level that is Star Alliance Gold. Oneworld has 3 elite status tiers across the alliance (although some programs do not have every alliance tier represented), so I'm not sure why Star Alliance couldn't also introduce an extra tier with additional benefits over Star Alliance Gold.
