512 blocks would reduce lag, but a few realities remain. Variance is still high with only 512 samples. Difficulty would swing more on pure luck than the current window. Isolation and timestamp attacks become somewhat easier the shorter the window gets.
Any change requires a hard fork and actual consensus. Just lower it to 512 is easy to say and hard to coordinate without creating more drama than the current system.

Monero’s every block adjustment is more responsive and keeps block times tighter under normal conditions. The cost is more algorithmic complexity and it still lags significantly after sudden hashrate shifts. Both designs work, Bitcoin prioritizes stability and simplicity over tight short term control. That’s why a near zero hashrate minority chain can sit almost frozen for a long time before difficulty can drop enough to recover
