Well, i can think of at least one previous situation in which i'd not be confident in changing anything about it even after a month. It happens when you're uncertain if what you're changing is going to break something that doesn't have explicit coverage or is mocked to a degree that the proposed changeset wouldn't cause the tests to fail. I remember a company that had a spelling mistake in a central location of their code. When this spelling mistake was corrected, errors started to pop up days, weeks and months later forcing a revert of this correction several times. So yeah, these things exist
