Yes. There is no other form of registration for UK citizens at the moment.
The EU Directive governing free movement allows
countries to have a system of registration but it does not force
them to have such a system. Some countries decided to make registering mandatory and others didn't. As far as I know, Greece is one of the countries that decided to make it mandatory, although you wouldn't think so since there is no real attempt at enforcement.
The Withdrawal Agreement gives you the right to continue living in your country of residence provided you are living there "legally"
by 31 December 2020. In a country like Greece, where registering is mandatory, you are only living here "legally" if you have registered. The blue and beige Residence Certificates are simply proof that you have registered.
In countries that did not make registering mandatory there will be some other mechanism to demonstrate that you are living there legally. Again, the Withdrawal Agreement allows
countries to use different mechanisms for UK citizens to demonstrate that they are living there legally but it does not force
them to do so. It isn't our decision, it's the government's decision. It would appear that Greece is only going to use the Residence Certificates as proof of legal residency. That is why it is vital to have one.
