Product Decisions This Supports

Enables standardized deprecation handling across libraries and applications, reducing technical debt and improving upgrade paths for users
Strong "buy" candidate for deprecation management: avoids reinventing the wheel with custom error-handling logic while providing zero side effects by default
Critical for roadmap planning when introducing breaking changes: provides traceable deprecation notices with issue links for documentation and user migration guidance
Use case: Library maintainers can safely trigger deprecations without interfering with application-level error handlers, while consumers can configure logging, suppression, or PHPUnit validation as needed

When to Consider This Package

Adopt when building PHP libraries/frameworks needing consistent, safe deprecation strategies that work across diverse environments
Ideal for projects with multiple dependencies where deprecation tracking/suppression is required (e.g., during major version upgrades)
Use when integrating with PSR-3 loggers or PHPUnit for automated validation of deprecation behavior
Avoid if: project is a simple application with no deprecation needs, already uses a framework with built-in deprecation handling (e.g., Symfony's native system), or has minimal long-term maintenance requirements
Not recommended for single-file scripts or projects with no versioned breaking changes planned

Executives: "This package ensures seamless customer transitions during feature updates by professionally managing deprecations. It reduces support tickets from breaking changes, demonstrates technical maturity to enterprise clients, and minimizes long-term maintenance costs—leveraging a trusted MIT-licensed solution with
