No, because this rule would change "how quickly" funds are lost. Currently, if a user doesn't notice his account has been hacked until the first powerdown hits (1 week), he loses 1/13 of this SP. Under this new rule, he would lose 1/4 in one week. Similarly, in two weeks, he would lose 1/2 of his SP under the new rule, versus 2/13ths under the current rule.
