Hi,
where were these mechanical automated changes discussed and what is your source for your changes ?

osm.wiki/Automated_Edits_code_of_conduct

changeset/146326932

e.g. traffic_signals=on_demand or traffic_signals=pedestrian_crossing, traffic_signals=*#Tagging

sorry, my mistake.
i had only paid attention to "central_key". restored with "centralkey".

Since when do we register illegal parking? Then every street where parking is prohibited would have to be marked so, because it is parked everywhere times wrong. Something like this does not belong in osm!
