People aren't asking for "any battery" to be legal, just USB batteries of some shape or form. These are common devices, with a known output plug, voltage, and current. A restriction saying "COTS batteries that output 5V power over USB at 2 amps or less and 10,000mAh or less" for example would be reasonably narrow, wouldn't result in these strange nightmare slippery-slope kids-wired-a-battery-at-home-using-bare-copper scenarios people keep jumping to, and would fix this and many other problems.
Chris, your interpretation of what's been posted here is very different from mine.

B) Make the only legal source of power on the robot to be the ROBOT battery.
There certainly is room for the rule to be expanded by the GDC without getting too crazy (such as allowing USB battery packs design to work with an arduino), but that's not what people have been pushing for in this thread.
