I guess the reason it needs a wrapper is because they are written in TIR instead of TE? Since AutoScheduler can only tune TE compute, it cannot tune such ops anyways. On the other hand, the AutoTIR that @junrushao is working on supports tuning for all levels so you may look forward it.
Meanwhile, I’m not sure how many improvements you will get by tuning such ops (e.g., scatter). There computes are not that complicate, so the tuning space is expected to be small.
