Every self-hosted developer bug report should have precise description and reproduction steps; console traces (or) source code references are appreciated.

## Bug description

OpenAPI specifications are automatically translated to 3.0.1, losing a lot a of the new features in later versions of OAS especially the security features such as OAuth scopes.

## Reproduction steps

Import of OAS yml translates to older JSON rendition, and Developer Portal does not have any feature definitions to work with.

## Expected behavior

Version 3.2 will have more security features and V3.3 is slated to have more OIDC features including CIBA.
We need these feature to tighten down what endpoints truly has access to, and limit the visibility of these endpoints to only those the user is authorized to use. They should not even see these endpoints.
Developer Portal will be able to filter

## Is self-hosted portal?
