They are not recording landmarks
Yes they are. Landmarks are simply defined as LIDAR map points that are consistent over multiple mapping passes. In a dynamic environment where you have parked cars, people, obstructions, you have to use LIDAR to map a particular location multiple times. Then you can use NNs or heuristic code to process each LIDAR map to remove points that are inconsistent through multiple passes. This is basically the localization point map.
When I say landmark, I don't mean they choose a building or house or street sign as a "landmark." Perhaps I'm using the word incorrectly, but you get my drift.
