Actually there is. I think one of the engineers posted a while back that oil cavitation happens at 7200-7300rpm for the ZF8 gearbox, so that's why they cannot push the redline further to 7600 rpm like they did with S55 & M-DCT.
Getrag DCT on the other hand is rated for 9,000 rpm, proven its stability at high rpm on multiple Ferrari and past M platforms.
