I lost a Mac laptop in the pre-MagSafe days, to a bullpen environment –a sysadmin was rushing to a meeting, snagged his foot, and took the cable and the laptop off the desk at high speeds.

After that, I was a big fan of MagSafe, but today’s USB-C and better batteries situation solves a lot of problems that MagSafe did in a different way. It allows for you to have multiple reasonably priced chargers, so the one on your desk can be safely placed, with a short unsnaggable cable. And you can still go to meetings and take your laptop home – because you have another cable in your bag and another at home.

So these days, I barely use the MagSafe cable on my MacBook Pro.

I agree with you, but in practice I've never had a problem with USB-C at all and everything mobile I own has USB-C except my face trimmer, and the next one will be USB-C for sure.

If you're worried about the port in a classroom environment you can use a short extension that you plug in on the device end, it will make the connection separate much easier if something unfortunate happens.
