        This endpoint is akin to the `SystemFeatureApi` endpoint in api/controllers/console/feature.py,
        except it is intended for use by the web app, instead of the console dashboard.

        NOTE: This endpoint is unauthenticated by design, as it provides system features
        data required for webapp initialization.

        Authentication would create circular dependency (can't authenticate without webapp loading).

        Only non-sensitive configuration data should be returned by this endpoint.
