That's fair, of course, but the method is still interesting and novel, and may even have security implications if it can be evolved to target locks containing features beyond the basics.
Not without spending time at the lock, performing an activity that is obviously criminal to any witness, and having to repeat that every time you want access to those premises.
And, also: a neophyte lock picker will likely leave evidence, like scratches. If you have a key that works, you can open the lock without any traces of picking activity.
Plus, in the majority of break-ins, does knowing how they got in matter? If someone broke into my house and stole my valuables, does the fact that they picked the lock make all that much of a difference? I mean, I'd almost be relieved they did that as opposed to something more destructive.
(For the record, I have security cameras, please don't pick my locks)
