There must be many more reasons for 'booking' routines.
During ab inition PPL training at Mascot (Sydney) in 1969, we were required - at least when leaving the circuit - to book out where we were going to fly, to comply with "SAR Watch".
[Search & Rescue].
Nowadays as a UK "airfield" operator - i.e. a grass field - in common with many others we keep a 'C' book for pilots to log their flights after arrival.
The Police seem to find its availability helpful & the accumulated movements, particularly over the first 10 or 12 years from starting the strip, are evidence of my Common Law rights for the land's 'change of use': all without submitting a Planning Application.
