Tras consultar coa comunidade española, alguén apuntou a esto que aparece na wiki:

> Once there is no real risk of remapping them by person thinking that this objects are still existing such elements should be deleted from OSM.

Esto non me constaba, a miña idea era que se podía usar o ciclo de vida a modo de histórico, xa que na propia wiki hay exemplos que así o fan:

 highway = pedestrian
 highway:1974- = pedestrian
 highway:1932-1974 = primary
 maxspeed = 30
 maxspeed:1957-1992 = 50
 name:1871-1933 = Kaiserstraße
 name:1933-1945 = Adolf-Hitler-Straße
 name:1945-1953 = Stalinstraße
 name:1953-1990 = Ernst-Thälmann-Straße
 name:1990- = Konrad-Adenauer-Straße
 ref:1932-1960 = R 96
 ref:1960-1990 = F 96
 ref:1990- = B 96
 surface = paved
 surface:1890-1927 = cobblestone
 surface:1927- = paved

Entendo que este exemplo está esaxerado e non debe ser usado en edición real.

Todo aclarado pola miña parte. Gracias.
