Well, that's every browser in existence, since all of them have gaps in 
CSS support.

Well, that does it. You've just officially stated that CSS isn't important 
and can be ignored completely. In other words, if it doesn't work 
perfectly in Lynx, it flunks.

We've talked about this before. We're *encouraging* authors to use CSS. 
And in fact they always are in CSS-aware browsers (which is everything 
these days save for Lynx, Links, and W3M), even if they do not specify a 
stylesheet themselves, because browsers have their own embedded default 

Moreover, CSS can affect and generate content, as through display: none, 
visibility: hidden, and content-before:.

Linear reading order is a 1997-era concept based on exceedingly simple 
1997-era HTML. We don't live in that world anymore. Why is it so hard to 
get rid of outdated WCAG 1.0 provisions in 2.0?
