The positive elements would be a more pragmatic approach to converting existing ICAO Pilot licences/certificates and ratings to their EASA equivalent, something it seems they are trying, but struggling to do, because the various CAAs around Europe have vested interests in making people spend money on compulsory theory training and examinations.
The conversion route of itself, not to mention the huge unwieldy EASA structure is a huge solution looking for a problem. On the basis that Europe shoud be trusting its NAAs just as it is prepared to trust each other's judicial systems (somewhat misguidedly I think) then the simple solution would have been mutual recognition of national licences across Europe, perhaps subject to compliance with minimum requirements, just as aircraft on national registries are accepted internationally, thanks to ICAO. That in fact seems to be what EASA have been trying to do regarding recognition of FAA licences via a bilateral agreement. You don't need an involved and complex new licensing system to achieve that. Europe continually tries to reinvent the wheel at vast cost, then finding that the traditional round one we have lived with for decaades actually works well! While it does this it imposes huge costs on everyone associated with aviation, drives individuals out of the sport and businesses to the wall because their economic model becomes unviable.
