I would retort with, stop trying to chuck a SQL database everywhere.

The issue imho is that multiplayer synchronization (like Jazz) should rely on primitives(CRDT or similar) that you really can't hide under abstractions but should be part of the datamodel to allow for custom synchronization protocols for different parts of the datamodel or even exposing synchronization faults to the user.

An analogy would perhaps be how wrongly abstracted systems like CORBA and DCOM lost out (Even if you can run into them in crevices of enterprise systems) to things centered around HTTP calls or simpler message oriented systems like gRPC.
