At this point words get blurry. Is using CUDA or a compute shader "software rendering" or not?

I call it "like software rendering". Its certainly software rendering in spirit since no fixed function rendering hardware is being used.

		Yeah, it may not be in the spirit of 90s software rasterizing, but since you don't offload the transform, lighting, and rasterizing procedures to specialized hardware, you technically do it "with code". The parallelization goes against the spirit though.
