Pool exit requires individual key claims rather than automatic return

A question about deleting a pool and returning its participants' keys drew a procedural clarification from Dhruv: the pool could not simply be deleted, its genesis key had to be claimed after the applicable waiting period, and other stakers had to unstake and claim their keys manually. Exit therefore involved separate actions by the affected holders. The reply specified no duration for that waiting period and supplied no evidence that the assets had already been returned.
