Which is exactly what I'm asking for.

Perhaps because they didn't read the design page either !

SHIFT-DRAG with nothing selected would add to an empty set, so would do 
does exactly the same as DRAG, except that it avoids the possibility of 
a MOVE happening accidentally. Great, let's have both.

I use it frequently. It's particularly useful if a way is composed of 
segments which are too small to avoid easily selecting the nodes 
instead. So I (shift)drag over the way and then deselect the nodes I 
don't want in the selection pane. This avoids zooming in and out when 
I'm mostly working at a scale where all but a few of the ways are large 
enough not to need to do this. Maybe zooming in would be quicker, but by 
the time I've tried to get a hit on the way and failed and it somehow 
seems easier to area select.
