And if one isn’t implemented properly, harming the usefulness of the 
feature, such as width: auto; and height: auto; in IE, it is a bug that 
the browser does not know of and thus will faithfully report as 
‘supported’. Thus @required is not going to help e.g. the absolute 
positioning case at all, which is a major browser feature support issue. 
@required doesn’t solve it at all.

I don’t think that there are many cases that this will solve, really. I 
predict that this will mainly be used to work around browser bugs (just 
like I use ‘* html’ currently), and not to work around cascading 
fallback issues. And that web authors will not let @required will not 
test for the CSS features that they really need, but instead for a set 
of features that will specificly identify a single user agent, in order 
to work around its bugs (and not its incapabilities), exactly because 
the bugs themselves can’t be detected.

btw, in this particular case, width: auto is not supported in a 
position: absolute; context, but it is in a position: static; one. How 
is such a required mechanism going to distinguish between those two...
