Sorting LiteLLM GitHub issues by difficulty to implement. Higher = harder.

{
#24965 is harder because it requires correcting request isolation and sensitive-data handling in shared router state, redesigning what gets persisted in retry/spend-log metadata, and adding concurrency, regression, and compatibility coverage. #12118 is comparatively localized to callback configuration precedence and merge behavior across UI and config sources.
