Correct, none. I use Pihole for blocking. But the bigger point I think is that security conscious users are hesitant to employ extensions in general, even if some folks are ok with a couple select extensions they are still spooked by the general field.

DNS blocking has not been effective for probably close to a decade, with domain-fronting, L7 adware/spyware, fingerprinting and other trickery. Parent comment correctly characterized the lack of UBO as a net security/privacy loss.
