you're talking about humans, a civilization that cannot fully win the decades-long fight for one portable charging format, and proposing all governments get on the same page about their passports?
The machine readable printed parts are covered by an international standard
ISO/IEC 7501-1 [1].
So despite your cynicism, all governments literally are on the same page about passports.
What do people think organizations like ISO, ITU, ICAO etc do other than exactly this sort of standardization process of human activities that are common across national boundaries?
