This sound like quite bad if true (emphases mine) …
… Apple plans to deprecate some non-supervised restrictions at some point, though not immediately, in the iOS 10 series. The restrictions slated for deprecation are:
Disable App installation and removal
Prohibit explicit content
Disable iCloud documents and data
Disable multiplayer gaming
Disable adding GameCenter friends
These restrictions will become available only for supervised devices.
The result would be to make iOS devices like Android devices — restrictions require a mobile device management solution (schools and businesses, also packaged for home use).
The only way this could be a net positive for parents (and those who care for special needs and vulnerable adults) would be if Apple were to add supervision capabilities to iCloud.
I’m going to look for more information on this.
