Forget it. EASA has nothing to do with microlights, they remain under national rulings. AFAIK Germany is the only European country to make a BRS mandatory. Wouldn't be surprised about Austria and Switzerland, though, perhaps even Italy for the "ULM Avanzato" subcategory but I don't think so.
Last time I had a look at it they were trying to depress everybody under common regulations. Did they fail to grab the last piece of freedom now? That would be a little success story in all that mud.
