DeprecationMaps are data structures or documentation artifacts used in software projects to track deprecated identifiers and guide their replacement. They associate deprecated APIs, options, configuration keys, or endpoints with recommended alternatives, migration notes, and related metadata. The goal is to centralize deprecation information to aid maintainers and users in planning transitions while minimizing disruption.

In practice, DeprecationMaps support automated tooling that detects usage of deprecated identifiers and surfaces actionable guidance
Benefits of using DeprecationMaps include clearer communication of deprecated elements, smoother migrations, and more predictable release
