I recall this discussion coming up before, and some ATCOs said UK GA has only itself to blame.
A fair comment might be that nobody (who had the time + inclination to get involved) foresaw this consequence.
Look at the EASA FCL stuff. You are facing massive documents which only the most obscessive person will have time to read, let alone understand.
UK AOPA and PPL/IR are massively under-resourced, and AOPA would have been concerned mostly with VFR issues anyway.
