The Injection technology does have benefits for users, it's not just helping Daz with copyright control. The third-generation figures such as V3 have over 70,000 polygons, around half of them in the head, and there are head morphs which can have 30,000 lines. Without Injection morphs, they'd have to be in the .cr2 all the time. Aiko 3 doesn't have so many morphs, and doesn't use Injection, but is a big enough .cr2 to be awkward.
