More specific type for detailedDiff()?

[benallfree]

Would something like this make sense? If so I can submit a PR.

export type DetailedDiffResult = {
  deleted: object;
  added: object;
  updated: object;
};

export function detailedDiff(
  originalObj: object,
  updatedObj: object
): DetailedDiffResult;

I agree this would be useful.
