The ability pages for Holy Steed and Unholy Steed are still in the '10 percent Runspeed Mount' category. These pages are no longer accessible, however, and the category tag can't be removed.
Edit: The Holy Steed and Unholy Steed items have not been added to the '25 percent Runspeed Mount' category but it's unclear whether these give new abilities (with a different ID) that I just can't find or what so I'm leaving them alone for the moment.
