I don't feel it is that new, but maybe that's because I've used that trick in other places. I think it's pretty common in a "type-safe C" way, and it should probably be encouraged. A unique pointer type for special usages, that you can't dereference even by mistake.. But adding a few comments might certainly be worth it. If only to teach others the trick.
