Actually I think they did, with the release of version 8.1. at least that's the way I see it.  None of the issues in 8 exist in 8.1 as far as the "abandoned" geometry is concerned.  But as Misty pointed out, fixing 8 is not an option because so much content was created by a whole bunch of artists, that would no longer work as intended.  So rather than fixing something, it's better to update, and generate a new revenue stream with a new product, while still keeping the old product viable.  I'm actually getting comfortable with 8.1 and it has actually become my go to figure.  The benefit is that I can use most of the stuff for G8 on G8.1
