If they want to get these things into schools it would be insane to expect the schools to also supply everyone with AirPods or some other kind of wireless headphones.
AirPods have too much latency for playing music. You want wired audio for running GarageBand or Logic Pro with a MIDI controller. They could have gone with a USB-C to audio adapter, but then you wouldn't be able to plug the MIDI controller and charge the computer.

This seems to be a recent phenomenon. A lot of electronic music production uses the Macintosh and Logic/Ableton workflow, to say nothing about how many of the best DSPs were Apple-exclusive until about a decade ago. I don't really think music production, at least in the EDM and hip-hop world, got popular on the PC until the rise of Fruity Loops and FL Studio, but that's available on the Mac now too.
