Hello - I've reverted this changeset (revert changeset #162830375).  These are not primarily sidewalks alongside roadways, but rather foot paths linking pedestrian areas, buildings, and parking lots to one another.  Not all footways are sidewalks. In this case, the original foot path tags are generally more accurate.  

This follows prior guidance received from the OSM Slack #sidewalks community: https://app.slack.com/client/T029HV94T/C6E4S4CQG
