Though it adds 0 pick resistance, it does add to key control. It is not meant to be an additional security measure the way we think of it, just key control. I'm not saying that's a super-awesome addition to a lock, but the only people who play it up as a failed attempt at added security are lockpickers. It's
just about key control.
Schlage Primus' 7th sidebar pin position is another
I don't disagree with that, but I also haven't studied the development of the Primus too closely.
and mul-t-lock's interactive floating element is also a good example. (It certainly made making your own keys from scratch more difficult)
What about DOM? Or any of the dozen other European manufacturers that now have interactive elements in their keys? Those weren't about adding life to a patent, it was because France changed the patent rules altogether, saying that you could not receive a patent on a key if it did not have some movable part. They weren't gaming the patent system, they were adapting to new demands from that system.
