It’s the new rigging that started with G3. Exporting cr2’s works fine for G2 hair.

It's not the rigging, it's the grouping. Genesis 2 hair (and some genesis 1 items that have Poser companion files) would work because a lot of the products were set up to work with the DSON importer for Poser and companion files. Because poser doesn't support Dual Quaternion weightmapping of Genesis 3 and 8, the requirements for content to work in poser (which most PAs including myself were encouraged to do, especially when selling content to DAZ) was dropped.
