> altering a sidewalk=* value on a highway track is inappropriate, given that such tracks with a surface=grass typically do not accommodate sidewalks in this region

why inappropriate? this bot is NOT adding new values, it is only moving already tagged sidewalk=none to sidewalk=no

also, apparently noone (including you) considers presence of a pointless sidewalk value a problem large enough to remove it from https://www.openstreetmap.org/way/224371993

> It would be beneficial to restrict such changes in your bot's activities.

can you be specific what kind of change you propose?
