No demand for a 'kids corner'?

I've seen and read a lot of posts about what improvements people want in iOS but I haven't seen anything about a demand for something similar to Windows Phones' kids corner. The go-to device(s) for young kids seem to be iOS devices so I'm surprised this isn't something that gets more attention. do you guys have any interest in having a kids corner in iOS or is it something else that microsoft created that the general population doesn't care for?
