The validator complains about colinear ways? Wtf? Definitely best
practice, as far as I'm concerned.

(By sharing ways, I mean that several nodes are part of two distinct
ways - not two nodes almost on top of each other.)

Btw, I'm starting to question the fact we don't do it with roads
though. The logic goes that the line represents the middle of the
road, and having an area touch the line would mean that the area goes
up to the middle of the road. I would argue that the line represents
the middle of the road *plus an arbitrary width*. When a footway
touches a road node, it doesn't mean that the middle of the road is
the middle of the footway. It means that road plus arbitrary width =
footway plus arbitrary width.
