One of my favorite things about Jackson was being able to arbitrarily navigate through the document with a rich and fluent API (JsonNode) in jackson.databind, which this JEP at least conceptually borrows from with the JsonValue abstraction. Both of these are better than how some of the other implementations do it, where you are effectively working with glorified Map<String,Object>
Looks neat - would also suggest checking out https://typora.io as well, which renders WYSIWYG in the editor and does a great job with syntax highlighting. I use it for taking notes locally.
I post this not really as a rebuttal to your post, or the grandparent, but more of a "here's what success a couple of generations later" actually looks like and what some of its characteristics may be.
