It's like most attempts to make it 'impossible' to use a device dangerously or illegally. By selling it as such, you convince politicians and other people of limited understanding that such a thing is possible. The result is legislation that demands it, adding cost, complexity and failure modes to every device whether its wanted or not.
I have no problem with an optional device that warns you that you're in a restricted area and shouldn't fly the drone. It's a aid to memory and doesn't pretend to cover all the dangers.
I do have a problem if it restricts the device from flying near an airport but doesn't restrict it from flying over a crowd, too close to people, near an unexpectedly busy road, where it might scare animals or a thousand other situations that are dangerous.
The answer to this problem is education and law, not auto-policing.
FWIW, I don't own a drone and have never flown one. My objection is entirely a point of principle, not merely to someone spoiling my fun.
