Related, I’m going to deprecate https://github.com/getsentry/sentry-conventions/blob/main/model/attributes/resource/resource__render_blocking_status.json because I think we should reserve the resource.X namespace to OTEL resource attributes. We can just rename resource.render_blocking_status in the SDK.
