See: > > https://wiki.openstreetmap.org/w/index.php?title=Key%3Adisused%3A&type=revision&diff=642985&oldid=567060 the first usage of the abandoned: and disused:-prefix seems to go back to 2011, with noticable use since 2013 (checked for :amenity, highway and railway). Usage for abandoned is higher than it is for disused (seems logical, as an abandoned feature is probably deterioated, while a disused feature should normally still be usable, just not used, so disused=yes may make sense in a lot of cases, because the main tag might still apply, while abandoned=yes would often be a misrepresentation, because the main tag would not apply any more) E.g. an abandoned:building is probably more a ruin than a building, while a disused building is still a building.
