By default it uses package.el, but there is an option to change it.

To me :pin would make perfect sense, as it explicitly expresses what
archive we want to follow for package upgrades.

One idea would be that use-package would check :pin and then
conditionally bind `package-install-upgrade-built-in' when invoking
`package-install'. That being said, I am not a fan of the user option
any way, and wouldn't mind if we came up with a cleaner solution.

Just as a "parachute", one could obey the global `package-install-upgrade-built-in`
value and make :pin cry out for built-in packages when the user indicates a repo and
`package-install-upgrade-built-in` is nil
