The change to 9000 introduced new technology such as the need to trim the front deraileur, the need to constantly replace cables for fear of them breaking right at the shifter, cassettes that explode, cranks that crack and break and lighter shifting. So not only do you get an extra cog that nobody needs for time trialing but a host of other benefits to go along with it.
Dude, that's not a new feature. They had it since DA7800!
I have a 2008 Trek Madone with DA 7900 among others. I've broken brake cables at the shifter several times and all my bikes are well maintained. Other than that, I've had no problems with the older version. I have DA 9000 on a 2015 Argon 18 Gallium Pro and so far so good.
Edit - maybe it is 7800, I don't really remember, but even so, it did NOT fix the cable issue.
