Yeah, I don't have my finger on the pulse of the CUDA users here. I think we want this patch to match the current behavior with `--cuda-include-ptx` as it seems to make the decision whether or not to include it at job creation time. We could then potentially change the default of `--cuda-include-ptx` if that's the preferred solution.
