We always have this discussion in these threads. There should be a HN wiki for these things. It's not just a name because it does measure true progress over time. We should just use density of transistors per area because that is increasing at the same rate as the name of the process is decreasing. It's just been done in other ways than just shrinking every feature. This article is about one of those steps in the design of the transistor that allows for that density increase. That 3 nanometers is not a feature size doesn't mean that it's "just marketing" either like it's often claimed. The process node scale does measure true progress. It's just unfortunate that we ended up with feature size instead of density for that scale because of historic reasons.
