We deliberately chose not to use JSON Resume because we wanted greater flexibility. For example, in RenderCV, you can use any section title you want and place any of the 9 available entry types under any section. In contrast, JSON Resume has predefined section titles, and each section is restricted to a predefined entry type. For instance, you must use the experience entry schema under the experience section.

I hear you. This boils town to personal opinion. I would have preferred to use an existing standard than introducing yet another one. The custom sections aren't something I've ever seen or needed anyway.
