ABA replacing OT?

Hi everyone.. new grad and new school based OT here. Does anyone else ever feel like ABA is slowly replacing OT services? I have seen more ABA therapists at my schools than OTs. ABA/RBTs are recommending sensory strategies left and right when it feels like it may be more of our area. Maybe sensory strategies are within their scope as well but I feel like as a new grad in the school systems our role is very vague and hard to understand.
