This is the sort of thing nobody needs or wants at this point in time.
Personally, I find this at the very least interesting and possibly useful. The lack of comments in JSON is a problem when it comes to annotating configuration stored as JSON. But we have other formats that do not have this limitation (INI, YAML are two examples).
I really like the idea of "Human-Optimized" config, because it is more important for code and config to be understood by humans than by machines.
No complaints about hocon itself, but Typesafe configs get applied in first-value-wins which is a continual source of ... amusement ... for developers.
