I would figure that new ring spacing means derailleurs with different stop positions, but havent seen this confirmed.
I am using a 9100 front derailleur with 6800 shifters and praxis rings on a rotor 3d+ crankset on my road bike, works great. The only place you have to worry about compatibility is using the 9100 or 8000 crankset with older derailleurs.
