I would like to believe that, but what about backward compatibility? What about user agents that do not use styles? There needs to be a fallback.

But, once HTML5 becomes a recommendation (and if "required" is a feature) I would expect browsers to do native parsing of the attribute resulting in some default highlighting behaviour AND in the case of accessible user agents conveying the semantic fact ("required") in a non-visual way as well.
