Yes, probably, I see your point. But still I think moving WP is essential and should be as easy as possible. The most often action, correction if the auto created route...
I realized, sometimes drag+drop works, somehow? But I never liked that magnifying glass method. With that zoom and your finger on screen, I have not a good overview.
Edit: it works, when a wp is quickly dragged. Here, while dragging, one also cannot change zoom.
