Two things...
Tapered tangs are still a thing...both in forged and stock removal knives depending on the maker. There's a tremendous number of talented makers out there, all you have to do is put in the work and look for them. The custom and handmade knife forum on bladeforums.com would be an excellent place to look and pose questions. (Years ago I used to moderate that forum.)
Taking nothing away from Loveless and those who make knives in his tradition, there are many makers who are every bit his equal in terms of talent and ability. That said, Loveless is responsible for much of the popularity that ensued and for that alone he would deserve the lofty place he occupies in the knife maker pantheon.
