Adding a new feature to the internal API: the ability to manage high available instances by having the platform determine and maintain a 'primary' instance from a pool of instances hitting this endpoint at a regular interval.
This is a lease-based leader election for active-passive failover. Instances will check in every 30 seconds or so, and the platform will maintain the primary until it either drops off for a couple minutes, or reports itself as unelectable. Then the platform will determine a new primary.
Applications can use this response to perform tasks only one instance should do while maintaining high availability, etc.
