I would make a WAG that PI and other companies won't suggest a solution with a "home-made plug" for liability reasons. Anyone instructing someone on how to assemble the plug risks explaining to someone who has no knowledge of electricity and who may "interpret" that to make the plug, "you just wire up one of the pins to ground".... That could spell disaster if the "novice electrician" wires the hot lead to ground rather than the neutral lead..... So I'd guess that PI has a "hard and fast rule" to not instruct people how to "work around the safety features" and someone in their telephone support section who instructed a caller on how to build a "bypass plug" would probably put the company in a heavy liability situation if someone's kid was electrocuted and there was any way to link the plug to PI's instructions.....

Sort of like Ford instructing customers on how to bypass the safety belt interlock and the air bag switches.....
