shop=Dépôt_de_câbles ? What is the meaning of that shop value? What kind of services or products are sold here? Is anything from osm.wiki/Key:shop fitting? Maybe new value needs to be invented? Maybe this data is wrong and there is no shop here? Maybe it is not a shop but something else?

(if anyone wants I can provide list of weird shop values in some country/area - let me know if you are interested)

is Cavavin (shop=alcohol) closed all the time? Then almost certainly it should not be tagged as shop=alcohol And if it is not always closed then opening_hours=closed is wrong

osm.org/node/1195362207/history ma tylko name=Clockwork Bits Software - ma ktoś pomysł co to może znaczyć? Czy kasujemy jako pozbawione wartości?

is maxspeed:source intentionally used instead of source:maxspeed ? See osm.wiki/Key:source:maxspeed

maxspeed:type is also sometimes used as a key for such data, see osm.wiki/Key:maxspeed:type
