Is there an argument to be made that 3rd wave ska without horns is technically punk rocksteady and not ska?

Are bands like choking victim, catbite and rancid, technically punk rocksteady. To a point it’s really is just distorted and faster rocksteady… HOWEVER There’s more that separates ska from rocksteady than a lack of horns. Rocksteady does away with walking bass lines and has more fluff In between the ands. I think it’s still ska but I just wanted to humor the question because it never hurts to question everything.
