Safari is still the new IE. Well, not really "new", it has been IE all along. It's the only non-evergreen browser that remains, and I don't get why this isn't mentioned every time Safari is brought up. All of their spec implementations are meaningless when the only version that matters is the one forever stuck in whichever oldest iPhone n% of people still use.

Caniuse is pointless, their new "baseline" score is pointless; as long as enough people keep using their (perfectly fine and working) iPhones after official support stops and as long as they are not allowed to install a different browser (engine), that's the only data point you need to look at when choosing which browser features to use.

iPhone or iOS has the highest upgrade percentage of OS. ~85%+ are on iOS 18 or higher. Liquid Glass iOS is the first time update has been slower. But Apple generally achieve near or over 80% of latest iOS by end of its cycle i.e coming August / September.

One could argue Safari on iOS being like macOS where it could be updated standalone, but current rate isn't too bad.
