Is there effectively any difference in the X1X designation and the older term "Maison Keying"? (Other than the fact that Maison keying used to be for the front of buildings or large boarding houses, now considered insecure) Is it only officially Maison keying if *all* of the change keys work, without exception? EDIT: ah, you seem to clarify this later in the video 😉👍
