 - Stable and non-experimental features that compliant to specification, and have a feature flag to minimize compilation size. Example: feature flags for signals (like `logs`, `traces`, `metrics`) and runtimes (`rt-tokio`, `rt-tokio-current-thread`, `rt-async-std`).
-- Stable and non-experimental features, although not part of the specification, are crucial for enhancing the tracing/log crate's functionality or boosting performance. These features are also subject to discussion and approval by the OpenTelemetry Rust Maintainers. An example of such a feature is `logs_level_enabled`.
