I guess the rationale was making it easier on the tendons in the carpal tunnel. Click, hold/move, click became click, move, click.
I would like to see a mode where the node that will be moved is autoselected based on proximity to the mouse pointer. Then it would become move, click, move, click. Obviously this needs to be guided by a rubberband, whowing which node will be moved. In JOSM this "improve way accuracy" also allows Ctrl-Click for adding nodes, I mean vertices.
