I think, more important that what is added in EA, is what will be added/changed for 1.0.
There are EA that aim to provide playable, constantly evolving experience. From what I understand BG3 is a testing ground. The fact that improvements aren't ported from live code into EA build doesn't necessary mean that those changes aren't happening. Who knows what is and isn't improving though.
Finally, someone realized it! I am surprised by people who count time to release based on EA update. These are two completely different clients, and as Swen said, our experience on release will be different. I hope that it will be so.
