While trying to follow the steps from https://github.com/cloudfoundry-community/capi-openapi-spec/blob/main/docs/getting-started.md#uploading-application-code using the OpenAPI document, I found that the `POST /v3/packages` endpoint, described at https://v3-apidocs.cloudfoundry.org/version/3.195.0/index.html#create-a-package, is missing.  I don't think it's possible to deploy an app due to this.
