I agree with you if "pipeline" has the narrower meaning I think you're using. In a more general sense, though, I use a Mac all the time in my software dev "pipeline", but I'm much more careful these days to strenuously avoid using anything on the Mac that I couldn't take with me to the next platform (which won't be iOS) once Apple courageously removes enough usefulness from new Macs that I give up and move on.
