I’d want a registry that was compartmentalized meaning each app gets an area to store its own configuration and the apps can only modify their own settings (without root permissions).
Apps should never be expected to modify system settings directly but only through system calls.
Some Linux packages achieve this kind of behavior by adding an additional user which owns their configuration directories. That always felt hacky to me.
