Disappearing Aerodromes

Hello everybody I am new here.

I originally posted this on the Key Forum, but have been asked to post it on here.

I have a ppl and fly an Auster. I use 1/4 mil charts to navigate by, as I generally don't go very far very quickly, (most people use 1/2 mil). The CAA email you updates to the chart during its life. These are some of the updates to the current England East Chart (issued June 2008);

DISUSED AERODROMES
Delete the following sites in toto - they are no longer visible from the air and therefore of no navigational use.

CHELVESTON at 521816N 0003157W (retain "Aerials" annotation)
GRAVELEY at 521546N 0001130W
LINDHOLME at 533312N 0005757W
POLEBROOK at 522753N 0002315W
TWINWOOD FARM at 521056N 0002927W
STRADISHALL at 520755N 0003044E
WARBOYS at 522339N 0000551W
WORKSOP

Delete all reference to runway at disused aerodrome at 531936N 0010351W
SWANTON MORLEY - delete civil aero site at 524344N 0005739E with a site elevation of 155ft amsl.
Do not show as disused

SPEKE - runways at disused aerosite deleted
Delete all reference to the runways at 532034N 0025253W - retain disused circle symbology

HETHEL - site now closed - change symbology at 523346N 0011024E from civil aerosite to disused. Also remove elevation. Note: change runway pattern on 1:250,000 charts - active runway 06/24 should be changed to solid disused and 17/35 deleted in toto.

Had a browse round on multi map, the removal of Chelveston is particularly impressive. I thought this was open until relatively recently? I don’t know why they want the aerial annotation leaving on; I think they have gone as well. I struggled to find Polebrook, and I was surprised to see the runways gone at Lindholme, when did they go?
