 *
 * One obvious example is: child components want to show an UI indicator if
 * the address is an EOA or contract. But if this address is currently a
 * contract and it is an UI element of an existing transaction, it may be that
 * at the time (block) the transaction happened it was still an EOA (create2),
 * so it should be displayed as an EOA.
