Didn't know about that convention... The pavement you added was repaved all the way to the end of the street, except in front of new buildings that already had good pavement. The one ont eh opposite side was repaved a couple of years ago, and even has tactile paving!
I think sidewalks should be either added as tag to the street, or mapped separately for larger streets (boulevards) only or for all streets in a neighbourhood (like it is in the centre, for instance).
