I should expect to be able to run Windows on my coffee maker?
That's a bit of an exaggeration of course, but I do not think this is an important "need".
It's Utopian garbage. A top down "simple solution" that is appealing on the surface but deeply flawed in the complex interconnected systems of reality.
You can already buy an Android device if you want more flexibility, and you can even get a developer account with Apple and make your own custom software if you really wanted. But telling everyone that they must have what you have decided is important is a garbage idea.
