Regarding 'our' aircraft though, Permit to Fly and microlights (Section S), and similar classifications across Europe, EASA has yet to decide how they should be regulated.
Actually, there is no decision to make - it's nothing to do with EASA. The removal of 'Annex II' aircraft from EASA's responsibility is enshrined in Article 4 of the Basic Regulation, which can be changed only by the European Commission. In the UK, the regulation of 'Annex II' aircraft is, and will remain, the responsibility of the CAA - they may choose to continue to delegate responsibility to to the LAA (or, perhaps, not) but that is entirely their decision, not EASA's.
