It's not an issue specific to USB-C. There are also plenty of USB-A/Micro-USB cables that don't have the data pins connected. Typically this is only an issue with super cheap electronics that only use USB-C as a connector for power and don't really follow the spec.
I haven't heard of a phone coming with a charge-only cable. Especially because that cable is usually used for syncing to a computer (iOS)/transferring data from an old phone (Android).
