I haven't looked into this so I apologize if it's an easily answered question but... is this (MDM/ADC) something an individual can do for their own devices? I know it can be done at the organizational level for, e.g., employer-owned devices, but how hard is this for Joe Blow to set up for, say, his kids' iPads and iPhones?
Yes. This is a very old article I had written back in the iOS 9 days, it still mostly applies.
A few warnings:
1 - Changing an iOS device to "Supervised" will wipe it (so you can't supervise someone else's device and data).
2 - Backing up iOS devices over USB after requires that you keep the keypair, and makes restoring to new devices much more complicated. I would not recommend relying on USB backups if using this method unless you play around and understand it well.
3 - Be sure you set the profile to be removable only by wiping the device, or using Device Configurator, otherwise, the profile could be deleted to enable USB.
4 - One could wipe the keys completely to be sure that NO machine has USB access to the phone, meaning it would need to be restored to factory defaults for USB to work again.
