I'm sure many airports for many different reasons cannot meet the EASA design requirements just like many cannot meet ICAO and CAA standards. That's why EASA has such things called "Special Conditions", "Deviation and Action Documents (DAAD), "Equivalent Level of Safety (ELOS), "Alternative Means of Compliance (ALTMOC) etc. These provide a means for an airport not able to meet design requirements to provide the authority with safety assurance detailing the mitigating measures.
As for CAA vs EASA runway aiming point markings, that I would suggest is not the highest of priorities when considering runway safety issues.
