Norway and Switzerland etc do not have such a chip on their shoulder and accept ECJ, even without having a say in it. It's called pragmatism.
The UK said in the "White Paper" that they actually WANT to stay in EASA.
I think it also said that they could accept the ECJ in this particular area (I'm not sure about this last one, please check the WP for clarification).
But of course, the EU is unlikely to accept the UK "cherry picking", and if they don't sign the withrawal agreement (with the North Ireland backstop, etc.) the likely outcome it's a no-deal with the UK being out of every EU agency. So if we don't see a change in the negotiations (by the way, they are sitting today but nothing new is expected), UK will be out of EASA by April 2019.
Perhaps the EU let's UK license holders transfer to an EASA countrie beyond this date, nobody knows.
