My guess is that in addition to Apple just not caring, they have market research telling them that most users don't want this feature. I imagine that the average HN commenter is probably as far as possible from the average iPad buyer. The main usecase is for families, and it's introducing a lot of complexity for basically no return.
Yeah, and people having families is pretty rare: no more than a few percent of their market :eyeroll:. The issue isn't that people don't want it: almost everyone wants it! The issue is that the alternatives to the iPad for its use cases are almost precisely zilch, and so implementing this feature mostly serves to cause people to spend less money on redundant iPads.
