Your PD is not actually part of your Rx. That's why it's normally not included. Your Rx consists of a OS Rx and OD Rx.

No, but the law has a handwavy bit about "everything needed to get prescription lenses," which ostensibly would include the PD at plain reading since you can't make the lenses without it and it's based on medical information. Your stance vs. that one is the crux of the debate.
