If that's the case then the GUI app isn't open source and is a completely different product from the CLI version, and differently licensed. If the CLI version can't do everything the GUI version can, I'd be keen to move to a more open and honest platform, especially for something as personal as a VPN.
They are not the same things. The App Store Wireguard does not support certain directives that are included in the CLI version (see my comment further up the thread).
