As a newbie transitioning from Agisoft Metashape, I miss the classification of points as vegetation, building, car, ground, etc. I am usually interested in the Bare Earth or ground shots. I do not think it is too hard to code up filtering points based on slopes but adjacent 3D points, where they are too step, they are likely to be vegetation or a man made feature. Point color gradients can also be assessed to better improve the point classification/filtering.
