I guess the general idea is a bit like the JCR (Java Content Repository) – that unfortunately never really took off but also included stuff like full text search. As far as I understand headless CMSs are more or less ORMs with a thin HTTP layer. Which might be a good thing when you want to distribute (micro)services. Maybe a gRPC API instead of REST would offer more flexibility.
