Why is Godot limiting in making a voxel game?

Godot Version

4.4

Question

I was reading the documentation for the SurfaceTool and it brought me to the Voxel demo. In the README for the demo, it states, “Sticking to GDScript and the built-in Godot tools, as this demo does, is quite limiting. If you are making your own voxel game, you should probably use Zylann’s voxel module instead.” Why is it limiting? Is this just a pre Godot 4 thing that they haven’t edited, or is it really not advised to make a voxel game in godot? Thank you!

Here’s a couple videos on the subject.
