Comparing transition of something like rifle musket muzzleloader technology leap to trapdoor cartridge technology seems a bit of a stretch for sake of argument if trying to show the superiority of a 270 Short rattle battle to a 223 Rem rattle battle. A little military-industrial complex at work here perhaps or how the brass in think tanks sit around with too much time on their hands and come up with ideas on how to act important, act busy, act relevant or spend money. Caution seems appropriate here if for no other reason than history is replete with such cr!p. And,
@Wyatt Smith, your question about the potential issues with NATO or other shared, universal use/supply seems valid to me.
