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

{
Issue 21036 is harder because it requires provider-specific authentication changes across endpoint detection, credential resolution, and compatibility testing for multiple Vertex usage modes. Issue 12118 is comparatively narrower, involving callback configuration merge behavior between UI state and deployed configuration.
