With this information given, the question is, whether highway=residential + sidewalk=no
implies a foot=yes . And with implies, I mean, that it is considered *duplicate information* if this is tagged. Note that This is different to an unspecified information which can with relative certainty be assumed (by data consumers) to be X. ( See also https://wiki.openstreetmap.org/wiki/StreetComplete/FAQ#Why_does_StreetComplete_often_tag_the_absence_of_features.3F) I am unsure about this myself, it's certainly not mentioned in the wiki, but that doesn't have to mean anything.
