So to try and bring things back on topic and away from which tests to use, presumably from 1st January we can no longer use the EU Citizens passport lines when travelling abroad, or can we? What about EU visitors to the UK? Can they continue to use the E-Gates or not? Obviously use of the E-Gates is available to other nationalities now too, so my wife (US citizen) can use them when we arrive from the USA. Having seen the queues at immigration at BRU for those passengers without EU passports I'd hate to be in that boat now.
