This gets messy because you already have problems with (mostly substitute) teachers ripping out implants (ex: insulin pump), cutting wires/tubes, or preventing kids from using their phone to monitor blood sugar, etc because they try to be "tough" on the no phones rule.
Yes. There are a lot of devices that support people with disabilities that nowadays use a phone as their interface. In the past most had their own devices but phones are near universally available so they have become the go-to interface for most of these devices.
