I’ve noticed that while these changes are really nice as a consumer, there are some trivial non-tracking scenarios that Apple eliminates through collateral damage and they’re not always transparent about that.
For instance, on the web earlier this year(?) Safari blocking all third-party cookies meant a lot of embeddable iframe tech broke and some design patterns are no longer feasible.
Instead, they could have just created an isolate context that gives the child iframe no information about the parent. But they just blocked all cookies instead.
* Ability to toggle WiFi on/off per app, just like Cellular
* Restore sane Bluetooth and WiFi button behavior in Control Center http://www.youtube.com/watch?v=HGHQ5R3NwrA&t=0m20s
* Include (or even just allow) an application firewall app like Little Snitch
Yes, this last one is especially unlikely given that Apple is now breaking application firewalls even in macOS[1], allowing all sorts of mischief[2].
