The goal isn't education in how to make games or use a particular library. The goal is education in coding, and games are just the hook to maintain interest. Pygame Zero hides the bits we don't care about so they don't distract from the bits we do. Middleschool students might cope with full Pygame, but when you're teaching 8-year-olds who can't type quickly, getting a sprite on the screen without any boilerplate is an advantage in maintaining their attention.

Another advantage of Pygame Zero is that the author was involved in the creation of Mu, and so Mu comes with Pygame Zero pre-installed. Having to install Pygame via pip would be a challenge for many kids.

Anyway, Pygame Zero includes all of Pygame so you're free to introduce as much of it as you like.
