Do the app stores have per-country rules to decide a rating?
Maybe certain headers could be cryptographically signed. So like if your movie is rated PG by the MPA the MPA itself could sign a statement to that effect. Or a government could issue a social media company a license they could use to sign their pages as complying with some regulation and revoke their license if they don't comply.
