I can only answer to the last question. Yjs uses several performance optimizations to produce small documents (both in memory and in the encoded state). Since humans type relatively slow (<60 actions per minute), it is impossible for humans to create a document that has performance problems. I showed this in [1].

Relm [2] even models a 3d world using Yjs. I don't necessarily recommend doing this as 3d applications usually produce a lot more actions per minute than text applications. This required some workarounds and deep knowledge of how Yjs' optimizations work. But it's definitely possible.
