2Compatibility abstractions for optional dependencies. 

3 

4This module centralizes fallback logic for safely importing optional dependencies 

5like ``opentelemetry``. It provides standardized access points for these modules, 

6avoiding scattered ``try-except`` blocks across the codebase. Maintainers should 

7import optional dependencies from this module rather than attempting direct 

8imports elsewhere.
