The magic of CRDTs does not prevent this. They are in exactly the same boat as OT, prosemirror-collab and prosemirror-collab-commit. It can't be prevented. The problem is worse with CRDTs because they instantly destroy user intent in the conversion to/from their underlying representation, which is the XML document. See discussion with Marijn about, e.g., splitting blocks above.

Heya, cheers. I'm actually intimately familiar with the node splitting issue. I've created y-prosemirror backends(complete with edit history, snapshots, etc) and "rewrote" y-prosemirror in TypeScript heavily refactoring and modifying it for some crazy use cases.

Those use cases hit a wall with, and I'm a bit fuzzy, the Yjs data structure and y-promirror diffing algorithm destroying and creating new XML nodes; black-holing anything else that occurred in them or duplicating content.
