You're basically describing "progressive enhancement." People with disabilities aren't really more likely to load a site without JavaScript or CSS though, a site can still require JavaScript and CSS to operate. It does take at least a little more work to make a form work through POST and as AJAX-submitted JSON. To be accessible, a site should be robust enough to work even when everything isn't the same as when the web author uses it (users use keyboard and other inputs instead of a cursor, have different screen sizes, zoom or enlarge text, use Windows High Contrast Mode to replace the site's colors with their own choices, etc.). > Clearly for some things (e.g. Maps) that are inherently visual this isn't possible The first interactive online maps were static images with North, South, East, West arrows (links) to load the next image; having to load the whole web page again for the next part of the map is not nearly as nice as loading image tiles dynamically but it does work. Dyanamic tile loading also doesn't have to be done only by cursor or touch, you can still have on-screen arrows that can be tapped or keyboard operated to load more tiles (plus loading tiles based on keyboard arrow keys, WASD, etc. while the map is focused).
