I don't think we'll have to wait that much longer to be honest. ICAO know that the way they are testing CVD pilots is wrong and in fact doesn't prove that we're unsafe to fly IFR. I think what the Austrailians have got going is good and if that's successful other aviation organisations will have to follow in their footsteps.
RONTOM, There is nothing to stop you flying IFR in The UK with CVD restrictions on your EASA medical. You do not need a night rating to obtain the IR(r) rating, or indeed the new EIR or competency based IR. You just won't be able to use them at night.
