I'm the guy that had the BC Hunting regs amended to allow the transport of ML rifles in a hunting environment charged, but not primed. I was President of the Canadian Black Powder Federation at the time.
I was a flint shooter, and it did not occur to me to include anything regarding the likelihood of a flintlock being capable of discharge without the pan being primed. I knew better, but was comfortable carrying a unprimed rifle and when dealing with bureaucrats, simple is good. Time wise, I saw no difference between priming the pan and placing a cap on the nipple of a percussion rifle. An flintlock being transported with an unprimed pan and uncocked hammer is no more likely to fire than an unprimed, uncocked percussion rifle.
The "hindsight geniuses" immediately jumped all over me and I suggested what I'm suggesting now - if you don't like it, contact the government and ask for an amendment. You will likely be told that henceforth you will be required to remove the flint from the lock or have a mandatory cover over the frizzen, which most smart flinters have been doing for the past few hundred years.
