Just seems like common sense that if you are routing over someones ATZ you would talk to them.
I was always taught to, don't see the problem.
It might not apply to Stapleford, but it could be there is a temporary aerobatics box over the airfield, parachute dropping etc. These are reasons I can think of that might make a quick call very worthwhile before routing over an ATZ. Fair enough if you have done your planning you should know already but a quick call, 'G-XX blah blah radio routing overhead for known traffic' could save you spoiling yours or someone else's day.
I use to fly with a pilot who would say 'I never talk to them, I'm above the ATZ so why bother' add to that a thousand other lapses in airmanship and you'll understand why I say 'use to fly with'.
