@riotnrrd The fact that you don't have use cases for giving an iPad to your child doesn't mean that many other people have a use case to give their iPad to their spouse or their young or older child.
Btw I also want Screen Time and better multi-user support controls on tvOS. I really wanted to go all-in in the Apple ecosystem and use Apple Arcade and Apple TV, but it's impossible to limit the time with this system; I bought an Xbox to solve the problem 🤷♂️
