I thought slots don't really slow things down much and aren't the primary source of latency, isn't it more about cost and power? Adding slots back in would remove the cost and power advantages wouldn't they? And now using more SRAM to track occupancy of an extra layer of cache, or if not SRAM for that something adding more latency.
