The wiki clearly shows to me that all my remaining examples would be inappropriate to tag as highway=pedestrian, and I would prefer not to have to quote the article. At risk of repeating myself, Market Avenue, Market Alley, Mutton Lane, Rochford's Lane, and Market Lane do not fit any of the criteria no matter what way you look at it, and there still seems to be no issue with tagging Market Lane as highway=footway

Winthrop Street, according to the Wiki, should be tagged as "highway=pedestrian + area=yes" due to it being significantly wider than any other nearby streets and its transition to the Patrick's Street pedestrian areas being arbitrary
