This is already a thing in Clojure/Script, using datalog instead of SQL. Syncing datoms between Datascript (and/or Datahike [0]) on the front-end and Datomic on the back-end can be almost trivial, and there are libraries like Datsync for that [1].
This reminds me of open-ui [1]. The goal of that project is also to tackle fragmentation and allow interoperability between component frameworks and design systems. How does UI Playbook compare to it? Do you think collaboration between the two projects would make sense?
