Either we need to refactor the expansion to lowering, then modify this PR to match the semantics, or we integrate this PR first, then do the lowering refactor on the resulting code. I would prefer the latter then I can take the task to move `VectorLoadShuffle` creation to lowering afterwards.

That is fine with me - I just need to see follow-up RFE filed, and know that it will be taken care of by someone ;)
