RE: Examples of websites that handle linearization properly

Currently F3 is still a failure technique which requires the information to be available when images are not displayed.  Until F3 is changed we continue to flag this use.

https://www.w3.org/WAI/WCAG21/Techniques/failures/F3

Tests
Procedure
Examine all images added to the content via CSS, HTML style attributes, or dynamically in script as background images.
Check that the images do not convey important information.
If an image does convey important information, the information is provided to assistive technologies and is also available when the CSS image is not displayed.

However...isn't that particular failure more to do with the fact that in the past, browsers had inconsistent default background colours and that users may have also customised/set their fallback foreground/background in the absence of author-defined styles? If CSS is relied on as a technology, then it's nominally a pass. WCAG doesn't account for users disabling things like images or CSS (or forcing high-contrast, or anything else) directly, no?
