Ask HN: Have you had any success building a multiplayer app using GQL?

For building multiplayer apps with complex interactions and conflicts it seems as though OT is the current industry standard with CRDT making some new strides. However, it seems as though these technologies are fairly complex and come with lots of trade offs and nuance. For many less complex apps, it seems as though you could take a slightly more naive approach similar to [Figma's multiplayer tech](https://www.figma.com/blog/how-figmas-multiplayer-technology-works/).

I am curious if anyone else besides Figma has taken this approach and what their experience was. Did it end up actually saving implementation time and reducing bugs vs using a more established solution? Were you able to implement it on top of existing state management solutions like Apollo/GQL or did it require handrolling something?
