+`opentelemetry-sdk`: point the declarative configuration package README at the shared [language support status matrix](https://github.com/open-telemetry/opentelemetry-configuration/blob/main/language-support-status.md#python) in the `opentelemetry-configuration` repo, so Python conformance status lives alongside the other languages instead of being duplicated per language SDK.

+## Spec conformance
+
+Which fields of the configuration schema the Python SDK actually applies at runtime is tracked in the shared [language support status matrix](https://github.com/open-telemetry/opentelemetry-configuration/blob/main/language-support-status.md#python) in the `opentelemetry-configuration` repository. The Python column is the source of truth; update [`schema/meta_schema_language_python.yaml`](https://github.com/open-telemetry/opentelemetry-configuration/blob/main/schema/meta_schema_language_python.yaml) there when wiring lands or changes, and the matrix regenerates.
