go-floc

The v3 release requires migration from v2 with path updates and type changes, which can be disruptive for existing projects, as admitted in the announcements section.

Lacks built-in support for common patterns like automatic retries, timeouts beyond basic control, or integration with Go's standard context package for cancellation propagation.

Uses a custom context system with key-value pairs (e.g., ctx.AddValue), which might be less intuitive and more error-prone than Go's native context.Context for data passing.

The README points to Godoc for details and external examples, indicating a lack of comprehensive tutorials or guides for beginners or complex use cases.
