In theory it can be divided into 3 individual changes. But they have the same purpose and impact. And two of them (findOnlyInterestingUse and processTiedPairs) are very small. So I sent them as a single patch. The total changes is 78 lines, still not a big one. A lot of test cases are impacted, so it caused the patch looks very large.
