I dunno, JSON Schema seems to have certainly found a lot of traction where it makes sense--web responses, etc. That may to some extent be a POV thing, as I work on a lot of OpenAPI-consuming and -producing systems myself, but I never really have to dig around to find schemas and the like for stuff I really care about. VSCode even has JSON Schema support built in, which is cool. I use that a lot.
