Lissart, the points that you attribute to EASA in your post (e.g. class E not being used for aerodromes) are actually ICAO SARPS and PANS. EASA is only acting on behalf of the EC to propose the transposition of ICAO materials into EU law (Implementing Rules) and to develop the associated AMC and GM. Class E airspace can be used around aerodromes but only as a control area, control zones must be class D or 'above'.
