In a world where DANE catches on on the web, I don't see why Google and Mozilla couldn't do that again. I mean, presumably there'd need to be some evidence of malfeasance, like there was with Web PKI. I don't see why Mozilla alone couldn't start by putting the screws to a smaller CCTLD and some medium-sized DNS hosts for instance.

That said, I don't particularly see DANE growing on the web.
