Most browsers don't do this. If you see a warning like that, it's usually triggered by javascript on the web page itself.
Safari added protection for 'unsaved forms' when closing a window/tab in v3, which was released about 9 years ago.
Great. I'll get right on installing Safari on my Ubuntu machine.
I didn't say it's available everywhere I said there is another solution (already working in another browser) besides removing a very long lived keyboard shortcut.

I think we have very different definitions of "everyone".
