I mean... hang on there. The sandbox, while questionable at first, has slowly been improving and at this point gives the same features as the web you're describing. If anything I find the APIs more feature complete, albeit less well documented as... well, let's face it, this is Apple and macOS we're discussing here. ;P I'll also note that "requires more skills" seems like a bit of a blanket statement to me. They're just different sets of skills.
