Oh what fun, I remember well Bob Pooley complaining about the amount of time and cost he went to in producing his company's JAR-FCL logbook.
Sensible, but one can imagine Pooleys and a few other companies being somewhat peeved after the amount of effort put into complying with what seemed at the time an over-complex but set-in-stone piece of regulation.
