Perhaps, but the physics of the smaller screen means that expanding text and/or other content is more constrained. That’s a good reason to keep 1.4.4 at a lower threshold without a 2D scrolling prohibition.

The whole concept is enabled by media queries, which were designed to enable reformatting for mobile devices. Would you rather not have an SC that effectively works on desktop?

For HTML, PDF it is not an issue, but if we were including Flash/Silverlight it would be different (which is why I’ve been asking that question). The plugin ‘formats’ are essentially black-boxes to the browser, so over-riding styles wouldn’t work, any mechanism would have to be author provided.

There are two questions, one is about formats (until we agree to disregard the plugin formats of Flash/Sliverlight), the other is about UA support/features.
