Poltergeist,
The exercise may well be simply to cram as much as possible onto as small a piece of real estate as possible. We're likely to see all these places you've listed, not suitable for use by Tornados and Typhoons, stay open to accommodate all kinds of odd ball units coming and going, with no aircraft in many cases, while somewhere else one of the four remaining operational bases in 1 Group disappears. But although I've just said it, I can't see the logic in it.
