If you're launching a wallet, should it be an EOA or Smart Wallet (4337)? 

EOAs become upgradeable with 7702 later this year, so you get the benefits of 4337 wallets and can upgrade to better standards over time. 

So it comes down to: upgradeable smart wallets (EOA + 7702 + 4337*) or pure smart wallets (4337 only) ?
