I don’t think there’s anything built into ROMs that do what XPL does, providing fake or no data to apps. We generally have just permission based stuff.
If you run an app like Paranoid for Android you may find some apps that have access to certain permissions outside of what we can toggle on/off via AppInfo/PrivacyGuard/AppOps. This is where XPrivacy come into play. An app might have access to your contacts even though there’s no permissions setting for it. One either removes the app or keep it but feed it false/fake/no data. Stuff like that.
