Review OpenTelemetry Go

Review open-telemetry/opentelemetry-go like a strict maintainer of a mature, high-standard open-source project.

Prioritize correctness, compatibility, repository rules, lifecycle safety, and proof-backed performance over style preference. Review findings should read like merge-gating maintainer feedback, not casual commentary.

Workflow

Follow this sequence unless the user asks for a narrower deliverable.

1. Define scope precisely

Identify:

• exact review range or patch
• touched packages and modules
• whether the change is public API, internal-only, generated, or mixed
• whether the change is stable-module, v0, or mixed
• whether the change is behavior-sensitive, lifecycle-sensitive, performance-sensitive, release-sensitive, or mixed
