Why not add tests for that? I don't really know how fusion is tested, but this summary implies that we should be writing tests showing how these things compose? And demonstrating the impact of this new flag.

On a different note, there's `lower{Un}Pack` and there's `DecomposeOuterUnitDimsPackOpPattern`. We should unify these things at some point.
