Thanks for the feedback, Flammable. I've updated the readme and main post so they use the actual cvar name, sm_backpack_ammo_stack_limit

Version 1.1 is ready and it includes your suggestions: sm_backpack_only_admins_can_wear and sm_backpack_only_admins_can_open. If either one is true then non-admin players will never spawn with a backpack.
