> Accessibility requires extra code. In Windows 10, UIAutomationCore.dll is about 1.3 MB, and will no doubt get bigger as Microsoft continues to improve the accessibility of Windows. But you can't write that off as bloat.

I'm convinced that's not true. Consider the case of CSS and ARIA roles. You could very easily write CSS/JS components defined on roles using CSS 2.1 attribute selectors, and accessibility just follows naturally. For instance, define your tab panels using role="tab", and screen readers should immediately understand it, while for visual designs, your CSS and JS just select on the appropriate roles. You then use classes for non-semantic content, like font and colour instead of using classes for everything as is currently standard.

So you're not duplicating code, you're writing better semantic markup once which can be properly interpreted multiple ways in different media.

Not how it's currently done, but there's no reason it can't be done that way, even for desktop UIs.
