Solana rent reduction status (SIMD-0437)
Where Solana's rent reduction (SIMD-0437) stands: the live lamports_per_byte, which of the five steps are live, when the next is expected, and whether a step is already queued on chain (it then activates at the next epoch boundary). Older accounts keep their higher deposit until it is withdrawn; each step makes more SOL reclaimable.
