yea was trying to see if I could skip the withdraw step and just directly send ETH, but seems like it might be risky

Creating and self destructing a new contract in the constructor prevents DoS

It's a trade-off. I don't know the code side, but one of the questions is who pays gas. Batch sending is much more expensive cuz you pay all the gas. Also, withdrawing prevents sending to dead wallets. If you have a claim window you can claw back what would have been wasted. Also, taxpayers prefer withdrawing.
