Yeah, good point.. although lyledriver seemed to have a problem with it.
I just measured, and my non drive pedal is further from center than my drive, by a bit more than what my chainline is off by... which means I'll get closer by adding this spacer (although my drive will go out by the width of the spacer, it'll still be more symmetrical. I really think I'm not spelling this word right). Looks like I'm in the market for a circular piece of metal.
