Have you tried it? I think "game changer" is entirely appropriate. It fundamentally transforms the user interface in a way that better reflects the needs of education environments.
As someone who's used many styluses over the years - they're all way too heavy, and the feel of pen or pencil on paper, is still far superior to any stylus to screen that I've experienced.
My younger brother wanted an iPad to do school notes on in University - that lasted about one week, and it wasn't the software, it's just clunky compared to pen and paper still.
When they get the weight down (of both the iPad and the pencil), the screen has texture, and the responsiveness improves by 2-5x, then it'll be a game changer.
For now, it's a useful tool in very narrow scenarios (artists mostly)
Well, as a comparison point I've completely eliminated paper for note taking in classes and general math/engineering work. The iPad with a quality Pencil-aware application (GoodNotes is nice) is better than paper, and doesn't feel any different to me in terms of weight and handling. The added benefit of, for example, being able to lasso and rearrange ink on paper as you work puts it over the top.
I own two iPad Pros, both with pencil support and have two Apple Pencils. I still don't regard it to be "game changing" for education, at least not in its current form.

Until we see software that reflects this, this hasn't happened. Hardware support is only half the story here. The iPad user experience is still fundamentally largely the same regardless of using the pencil or not.
Don't get me wrong, I think it's great to have and I can see why kids will love drawing with it. I just don't subscribe to the idea it's somehow a game changer yet.
