You already do share the UK airspace with lots of them......have a look at the minimum requirements for the restricted microlight licence and how few dual hours are required in microlight training.
With a grand total of 15 hours a person could obtain a restricted microlight licence bring that up to a total of 25 hours a microlight pilot could be unrestricted and fly round the world.
At least the French proposal limits pilots with little experience to A to A flights........something the UK does not even if they have as little as 15 hours when they get their licence.
Of course, there is also the solo student crosscountries.........how many hours do they have?
EASA bashing indeed.
