Anyone had problems with their DA9000 carbon cassette carrier disintegrating?

Was planning on buying a new Dura Ace 9000 groupset to replace my ageing 7900, but it appears from my web research that Shimano may have cocked up yet again by fitting a carbon cassette carrier for several of the sprockets, which spontaneously disintegrates for some riders. (I say again as IMO the omission of front derailleur trim for the big ring on 7900 was another failure).

Would a SRAM 11 speed cassette work well with DA9000?
