Why is it necessary to relate the highway=stop to the junction node?
Isn't it obvious that if a highway=stop is within a few metres of a 
junction, then its part of the same junction. It shouldn't affect 
routing software etc anyway.

And it doesn't have to be very precise. Its easy to estimate the width 
of a road, and how far away from the road edge the stop line is.

(and on a related note, is there any of mapping advanced stop lines (for 
cyclists etc)?)
