Apart from looking ugly the fake overlay on top of taxiways and ramps also hides detail in places. Worst offenders are where at some corner of an airfield there is an air museum with some aircraft parked outside - example Cosford in England. Part of the display of aircraft can be seen poking out past the crude polygons of ‘tarmac’ and ‘concrete’ and ‘grass’ hiding them.
Yet if not covered they look fine from anything over a couple of hundred feet up. There must be hundreds of similar over the whole world. They need to be removed - especially where there is no parking for vehicles or normal aircraft needed.
I noticed that too…STRANGE 
Yes it is sad because I decided to fly to every UK heritage airfield and museum site listed in The Aeroplane magazine. Most have at least some aircraft outside that would show up.
The ones sufficiently outside airfields show up nicely. By the way the Vulcan parked outside at Carlisle Airport has been noticed by the AI and is rendered as a Vulcan shape building (actually rather a neat Idea for a museum!)
