It's made worse by the standard size of an ATZ - gliding sites do not need a 2nm radius when the major danger is cables overhead. Maybe the response to the accidents referred to is better conspicuity, not more radio chat!
If you combine this with the planned BZN extension to the North it obstructs of a massive area to East/West transit.
Absolutely. Yesterday I flew back to Enstone eastwards between LR and the current BZN zone. The gap is only 4 nm, so an ATZ of 2nm radius will leave a single line to fly with 1nm either side and thus create a significant choke point. If you then decide to avoid the ATZ by flying to the north then Stow-on-the-Wold will suffer a lot of extra noise...
