The script identifies clusters of amenity=charging_station elements which are closer together than 20 meters - they are then candidates for being a site. If the elements in the identified group have common name, brand, operator or similar tags then they likely belong to the same site. Some elements will be different and should not be grouped. A few similar tags for the potential site have already been created in the file to speed up the process, but to be verified by a human. I do not think it is a problem that for example two adjacent charging stations continues to stay separate even if they could have been grouped. Sooner or later someone will come across them and consolidate into one element. > I don't see either how an algo will detect that an object > amenity=charging_station isolated represents a site of > several charging stations (and is thus valid in the new schema) > and not an isolated charging station (which it would thus > be necessary to modify by adding man_made=charging_station) > The script leaves isolated amenity=charging_station element untouched. There is no need to change them. They represent more than 80% of all charging stations in OSM. The proposal is designed to not require any changes to those. They already denote a place to charge an electric vehicle before the proposal and will continue to do so afterwards. Many of them did not have any information about the number of charge points before the proposal and they will continue to not have that afterwards (like many other things with missing details in OSM). Please note that you do not need to map man_made=charge_point at all, just one node for amenity=charging_station for the site. If you are interested in contributing, I would rather focus on the identified groups of charge points above.
