As SELF-DESTRUCT opcode is disabled in the cancun fork(unless the account is created within the same transaction, nothing to delete in this case). The account will only be deleted in the following cases: - The account is created within the same transaction. In this case the original storage was empty. - The account is empty(zero nonce, zero balance, zero code) and is touched within the transaction. Fortunately this kind of accounts are not-existent on ethereum-mainnet. All in all, after cancun, we are pretty sure there is no large contract deletion and we don't need this mechanism for oom protection.
