Why? For me at this point YOLO means a family of detectors that in a single pass propose a bounding box per pixel and filters them with some clustering algorithm. When I see YOLOfoo I know what kind of architecture to expect. A more descriptive name like YOLO-tricks instead of YOLOvX would be nice though.
Something called YOLOv7.
