Pegasus,
Many pilots, instructors, and examiners have complained that the current syllabus is not fit for purpose. What is wrong with trying to provide an alternative syllabus which better fits the needs of a modern PPL by providing them with up-to-date knowledge and skills needed to operate safely?
The old syllabus is unlikely to disappear as it is an Acceptable Means of Compliance. You can carry on with your head in the sand if you wish, teaching to a 1950s syllabus...
