You know, even back when SL had only the now termed legacy av system, there were a number of merchants making pre-made, boxed avs. It wasn’t a made-from-scratch mesh av (which didn’t even exist then), it was often a case of them having made adjustments to a shape so it had a particular look (i.e. more muscular vs more beanpole) applied a skin they’d made (once LL introduced the ability to apply textures to the av) and sometimes some clothes that fit the theme that packaged av was going for (green jungle savage warrior from Venus!)… so, no, I don’t really anticipate Daz av support killing the potential av-maker business in HiFi. It might put a dent in made-from-scratch HUMAN avs that aren’t Daz-devised. On the other hand, those who’d make new, boxxed avs for HiFi can now also turn around and sell them to those who’d use them in Daz Studio to make art renders and comic-book narratives, too. And that might also include the totally-made-from-scratch nonhuman avs, too, assuming the rigging works the same in Daz Studio as it does here.
