There is no immediate plans for that, because it will require CUDA Toolkit higher than 6.5 and we are not ready with such a bump yet mainly because any newer CUDA Toolkit causes measurable speed regressions. For until we solve or accept those regressions we can't go officially higher than sm_52.
I also don't see any cards which supports sm_60 [1] which means we can't really choose any reasonable parameters for stack size and number of threads. I also didn't find information if any of publicly available CUDA Toolkits supports sm_60. So what kind of secret hardware, drivers and toolkit you're using?
