That’s before Safari added better web component support. I would expect many sites and apps to not work at this point.

14.3 seems more like "try to degrade gracefully" old rather than "won't support" old...

Whatever it requires to hide the menu, that a 3 years old browser doesn’t have, can’t possibly be essential for just a documentation page.

It’s an 8 year old phone … iPhone 6s was released September 2015…

The issue here is the version of the webkit engine, which ships with iOS and that is 3 years old. Anyway a docs page is basic, it should be compatible regardless.

Works for me, 15.7.9, so updatable.

It’s extremely common to support the two most recent major versions, especially for iOS. It’s great if things work on iOS 14, but it’s been explicitly out of support for over a year in a vast number of organisations.

That's the well-established expectation for iOS.

The web has a pretty different set of expectations, one of the reasons for its success.

Not these days, where most people are using evergreen browsers and iOS users upgrade very quickly.

Take a look at the defaults for browserslist, for example:

https://browsersl.ist/#q=defaults

It just barely supports Safari 15, on iOS only, and that’s likely to go away imminently because it’s under 1% usage.

Browserslist is used by a huge proportion of web developers and the tools that they use, with millions of downloads a week. It has nothing to do with native apps and everything to do with the web.
