Here's a summary of optimizations.

1. **Simplified `context_settings` Initialization**: Initialized `self.context_settings` directly using a default dictionary if `None` is provided.
2. **Optimized String Concatenation**: Combined the handling of deprecation messages into a single statement to avoid repeated string concatenation.
3. **Removed Redundant Checks**.
    - Directly checked `self.callback` without `is not None` because non-None values are considered `True` in Python.
    - Removed redundant docstring comments for methods where context is self-explanatory.

These changes should yield marginal performance improvements primarily due to reduced condition-checking overhead and more efficient string handling.
