It's very much a work in progress, especially since overall progress is happening at the same time.
27 countries need to coordinate to first agree to grant the EU the power to take over some aspects and then those same 27 countries need to actually do the work, together with the EU, to standardize that aspect. Then the standard needs to be adopted and enforced.
The EU has less power than a confederation, which is a very weak supra-statal organization. So everything is very, very slow.
The EU is gradually able to do more and more, but the time frames are decades long.
