The difference being that each language-specific framework has their own way of implementing the specs with the problem that some are done well and some are done half-assed. But then again, this problem exists with many specifications (OpenAPI is not alone). I look at it like this: the spec should inform the framework which should inform the (language specific) implementation. If the language specific implementation is it's own framework then so be it, but counter to the intentions of the layer above it. So why do all this? Enterprises have many teams that have many capabilities. How one (Python) team implements OpenAPI is drastically different than how another (Typescript) team implements OpenAPI, which causes a lot of friction when moving engineers around to different teams. If a spec desires to have mass adoption then providing at least heuristics for implementation will only increase that adoption.
