This is pretty danged slick. I especially like the API to create your own components very intuitive.
One rotten egg I can spot: "Supported subset of Jackson". Ow. Jackson is unfortunately a land mine, rattled with CVEs over the years. This was mostly fixed by taking the best ideas from Jackson and standardizing them as JsonB, which not have several good implementations. I would highly suggest they drop Jackson support in flavor of JsonB just so the Jackson libs don't have to be on anyones class path.
