Discord Nitro Perk for longevity

Please consider adding a perk for long time subscribers to Nitro.  It would be nice to get an extra free server boost per numbers of years we've been active subscribers.  For instance, if someone has been a nitro subscriber for 2 years, they would get 4 boosts included with their subscription.  This would also aid the company's churn rate by giving a useful perk for customers to keep their subscriptions active.
