It seems like you're saying there is no need. More importantly, the "group" role is not identical to the generic role. Otherwise there would be no difference between <div> and <div role="group">... This is not a cleanup exercise. Changing all generic elements to be exposed as groups would have very broad and undesirable effects.

Should, for whatever reason, an author put tabindex on this useless element the user will receive a very confusing user experience that only impacts the user of the assistive technology as the user who is not impaired will see physical showed in the UI around the rowgroup. > > Asking the group to waste cycles finding a real world example where this element is used is a waste of people's time for something we just want to protect the user against in case it happens.

I can confirm that the AAPI group decided to change the mappings for role="rowgroup" to a generic group-like role for the various platforms [1]. The reason is that authors can create a grid with rowgroup elements that are focusable and interactive (e.g., respond to clicks) [2]. > > > > However, the statement, "This would be consistent with IE and Safari mappings" is not correct with respect to Safari. The current AXAPI mapping for rowgroup is "Not mapped". There is a webkit bug in this regard [3].
