> Let's say every consumer in a group has session timeout s. Currently, if a consumer leaves
the group, the worst case time to stabilize the group is 2s (s to detect the consumer failure
+ s for the rebalance window). If a consumer instead can declare they are leaving the group,
the worst case time to stabilize the group would just be the s associated with the rebalance
window.
> This is a low priority optimization!
