Firstly, the WAI proposal defines a means of establishing a hierarchical structure of option groups, as is required for purposes of accessibility. Since it is entirely compatible with existing HTML documents and user agents, as Dave Raggett has repeatedly pointed out, it is not necessary for visual browsers to implement this feature, though it would be preferable that they do so. No evidence has been offered which suggests that the current proposal would not be amenable to extension in the future, in such a way as to meet the concerns described above. By contrast, the objector's alternative proposal does not provide the basis for future extensions and, nor does it meet the WAI accessibility requirements. Basically, I think the objection arises from a lack of appreciation of the distinction between structure and presentation, which is a fundamental feature of HTML.
