This is the part that I find the strangest:
> We also dropped support for other very old browsers, including Edge Legacy, iOS versions earlier than the last 3, Firefox versions earlier than the last 2 (aside from Firefox ESR), and Android Browser.
Safari from iOS 16, released in 2022, is more modern in every conceivable way than MSIE 11. I'd also bet there are more people stuck with iOS 16- than those who can only use IE 11, except maybe at companies with horrid IT departments, in which case I kind of see this as enabling them to continue to suck.
I'd vote to rip the bandaid off. MSIE is dead tech, deader than some of the other browsers they're deprecating. Let it fade into ignomony as soon as possible.
It’s rarely a horrid IT department but some special or legacy software without modern replacement

There are likely millions if not tens of millions of computers still running MSIE11. There are likely to be no devices running iOS 16
“Support” here probably means “we’re testing jQuery for compatibility on those web browsers” - likely Safari from iOS 16 still runs this version of jQuery just fine. However, running automated test suites or support bugfixing for those clients is a lot harder than spinning up some Microsoft-provided VM with IE11 on it.
