Mapping footpaths as separate ways is interesting in some cases, but it is optional.

Since this is a large boulevard, it might make sense to make the extra effort to map it.  I have just added it.

@anonymous: We don’t mind being occasionally informed about missing data.  OSM is a hand-made map, and we are all volunteers, who spend (a lot of) our free time to carefully draw all those beautiful sidewalks, crossings, cycle tracks, roads, and more.  Unsigned notes that just blame us about missing stuff are often unpleasant to read, especially when some people (or one, posing as several people) open multiple notes all across the city.  Please give some thoughts about contributing yourself.  Thanks.
