Yeah, This rule already exists here in Canada too. My passport, my Ontario driver's license and my health card photos were all "no smiling" (I find that the person behind the camera often deliberately tries to make you smile anyways by telling a joke)

When I used to work for a certain international courier company I was always trying to talk people out of sending packages to Nigeria... It was usually PS2s that they were convinced they would get paid for AFTERWARDS... and they would have the Nigerian person's shipping account to send it on -- and of course, the second it was shipped, the Nigerian person's account would prove to have a cancelled credit card and a fake name. :/ Not a single one of those people EVER believed me that they were being scammed no matter how hard I tried to convince them. People are so willfully ignorant sometimes! And GREEDY! "OMG! I'll get $$? SIGN ME UP!"
