This is the number one feature on iOS 14 that I cannot wait for. I am getting very tired of finding out that unrelated services know that I have used a specific app (like Facebook knows way too much).

Somewhat related (even though this is focused on Apps). I have noticed an uptick in websites that don't support safari, likely due to how they handle cookies. I hope this does not become super common (but I can't imagine many sites wanting to loose out on the iOS market)
