I work in chip design on single digit "nm" processes. Interally we might say 5nm to refer generally and N5 or N5P to refer to a specific process. When you need more specific numbers you look it up. Exact design parameters are carefully protected trade secrets. Commenters on Hacker News care a lot more about this distinction than the engineers working with it. Nobody cares that it is not gate length or half pitch.
