This is just the first step in a bunch of cool stuff you can do. Now that the data is in a syncing database you can have models across multiple vendors and backends all working with the data locally while collaborating on changes. This means you can use the right model for the job without worrying about tracking where the data needs to go, instead each model can react to the appropriate fields and update types.
This is a super simple codebase so if you fork it and make something real, please share it with us.
