The whole "checkpoint friendly bags" thing is a TSA specific phenomenon. Security agencies in other countries have their own standards and do not care about what the TSA accepts (and some would argue that's for good reason).

In general I would agree that they shouldn't listen to the TSA. However, the checkpoint friendly bags do address the issue--for X-ray purposes the laptop
is out. Mine at least says "checkpoint friendly" in the laptop side of it, there's no question what it is.
