I don't have much experience with lidar, but I do with machine learning based approaches with photographic data. There has been a massive explosion in the last 5-10 years in filtering and processing algorithm advances that can more readily clean up false positives and insignificant noise. I would assume the barriers to high quality data are quite a bit lower now.
