For what it's worth I use 800x600 every day on my desktop.   So I am an advocate for support with low vision users without loss of content or functionality.  But from a practical standpoint we need some hard metrics to use for testing and right now SC such as SC 1.4.4 are missing those and thus we need to define something.  The next step and logical lowest denominator would be 320x200 -- but practically speaking I'm not sure what the push back on that would be.

As soon as that user makes their window slightly narrower than full screen, or if the user had a slightly older machine/monitor, that only runs at 1024x768, they'd then fall out of the "dekstop" and into the "mobile" bucket.  A dangerous generalisation, I'd say, only compounded by the possibility that WCAG 2.1 will go above 200% depending on how the LVTF SCs pan out.
