It's a quirk of their engine. If you watch some of their art streams, they talk about this limitation. Funnily enough, I was looking into how to change the vertex precision in blender, but I haven't found anything yet.

Vertex precision just means the data values attributed for vertex position.

8bit vertices would mean 256 different places in each axis the vertex could be, so if your bounding box is 5 meters, the minimum space between vertices is 2cm. You can see how this would affect the design of models since there is effectively a minimum feature size.

Also if you had a square that rotated in 8bit space, it would "jitter" since a truly smooth rotation would require the vertices go between the possible locations, so the nearest possible location is chosen.

Modern renderers use floating point values with big bit sizes, which effectively means you can place your vertices exceedingly close to one another.
