Flash Loan attack can grab millions of dollars from decentralized vaults in one single transaction, so this EIP would be meaningful.
Great!

Is there any relevant practice code available? I would like to study it. Thank you.

This is a meaningless ERC submission
Before this, using the hash value of “tx. origin+blocknumber” could also achieve the same function, which is to charge more gas.
