(A foreigner very cautiously making an observation, in all humility not affected by this legislation)
If other jurisdictions, FAA etc, decide that the EU PPL is not in accordance with ICAO, then EU PPL holders would find it difficult to have their licenses recognised outside of Europe. This would have major implications over time for recreational pilots and also for modular hour-builders.
Perhaps this might be why the LAPL (non-ICAO, non-transferable to other states) is treated in such a common-sense way compared to the PPL.
