“Kashrus” reforms leave an open door to anyone proclaiming to be a Rabbi, despite not even being frum but they’ll call themselves a Reform Rabbi, to be able to become a “mashgiach” and give heshsheirim. Now there may be more to this, but that’s the overall idea. Basically, the mashgichim won’t need to be Orthodox so if the Rabbanut hechsher which was kosher till now, it will be completely treif.
