This is technically a CRDT. It's just that the "order of operations" to apply over the doc is now resolved using a central server. For context, this is exactly how Google Docs and Zoho Writer works currently. Except that, they use OT with central-server based reconciliation and the proposal uses CRDT-istic approach.
I agree this is more practical if your service anyway run over centralised servers (aka cloud)

This is not true. One of the most basic traits of CRDTs is that updates are performed without coordination. Relying on a central server to coordinate conflict resolution rejects two of the main traits of CRDTs.
