(added in [Go 1.26](/doc/godebug#go-126)). This opt-out is expected to be
kept indefinitely in case goroutine labels acquire sensitive information that

## Log Message Guidelines

- Logger: `LogManager.getLogger(ClassName.class)`
- Format: `key=value` (e.g., `userId={}`, `url={}`)
- Prefix with `[name]` when context identification is needed
- Mask sensitive values (passwords, tokens)

**Important**: Return types or response models are what filter data ensuring no sensitive information is exposed. And they are used to serialize data with Pydantic (in Rust), this is the main idea that can increase response performance.
