Line Lock - front or rear??

You boneheads realize if you flip the line lock around, you can block brake pressure from the rear brakes, essentially accomplishing the same thing as plumbing the linelock in the front brake line, right? The only difference is your foot acts as the "switch" if plumbed in the rears, vs if plumbed in the front.

I've done it both ways and am curious what others prefer.
lol, guilty as charged!
