It's basically what I told my friend who's been flashing the phone, he said it didn't matter with all his other HTCs. I still am getting him to stock flash now, as he's equally unsure of what to do...
Update: Yup, was programmable on stock ROM, just as I told my friend. His face when he handed me the phone was priceless. I wish I had the phone in hand to take a pic and post it here...
Thanks Obvious.
