You'd think so! But unfortunately they only support old OpenAPI versions. OpenAPI v3 isn't supported in that way so I have to hand write my specs and it's just the worst.

I've been down this road. Some pieces of it might be, but there's a lot of structures in v3 that didn't exist before. The popular Go tools for older versions of OpenAPI aren't being updated for v3 because they're not interested in all the work required, so Go tooling is stuck in v2. This has been the state of things since 2017 when OpenAPI v3 came out. I'm sure some day somebody will build something that fits my requirements, but it just doesn't exist now.
