Ok i like it like that. Thank you. I try to keep things correct. Just focusing on airports. Several issues on other airports are dual definition of runways (i understand from my learning curve that it has changed in OSM from surface to centerline) so sometimes it's duplicated fro the same airport. Other  issues are coming from "runway" being used for a single object covering taxiway and parkings, i try to reallocate things correctly. 
No SW can accommodate from so many variations. i asked to be able to use "disused:aeroway=runway" when it's a rectangle (that accomodate for the main cases).
I know those RAF WWII airports are kind of exception, but there are still listed even disused.
