They are on an EASA permit-to-fly as a temporary measure with expected transfer to ELA1 when / if that is finalised. There are a small number in the UK, so I assume there will be in other EU locations too.
The EASA permit-to-fly is not connected in any way to the LAA permit system and the CAA has concerns about the situation. It is somewhat unclear what happens if the PtoF expires and ELA1 is not finalised. It is also unusual for an aircraft to be granted a retrospective C of A when its manufacturer was not approved at the time it was built. EASA may sort all this out, or it may be a bit of a disaster.
