The only reason the A380 (and the spitfire that also taxied up to the east apron) had the whole east apron was so the apron could be segregated and be returned to landside so that Rolls-Royce, local schools and the media would have easy access to the aircraft otherwise it could have gone onto a stand.
And also as andyy says the 727 is part of the fire training ground. The airport bought it from Air Alfa after it suffered an accident at EMA which was classified as a hull loss when it 'sat down' in strong winds... Previously registered as TC-ALM
