You can still watch those unproven heifers file in to get IVF'd on a weekly basis during peak breeding season, but it has slowed down some. In some cases you literally can't tell if you're looking at an Angus animal when they come down the alley. The $B chase was probably the peak of the ignorance and a lot of people learned some lessons during that deal.  

Their positioning to be a piece of the 4 way cross would have significant value if you could somehow protect the genetic pieces, but I guess I don't really see the point in becoming wagyu light when the wagyu and similar already posses the specific genes at a higher concentrated level.
