One of the few good things that have come out of EASA is the introduction of the Aerobatic rating. This at the least reminds pilots that they are not qualified to perform aerobatics until they are properly trained and assessed.
There is only so much you can do within the PPL syllabus before you overload it and possibly put people off flying. When I learnt to fly spinning was mandatory and many left flying because they would not accept the impending spin training or suffered an intolerable reaction to it. The current stalling syllabus is sufficient in its current form when it is completed fully. Sadly this is not always the case. As with some other parts of the syllabus stall training it is not completed, as detailed, but is only carried out sufficient to meet the requirements of the skill test.
