The problem we were seeing downstream was that other functions like `mlir::scf::tileAndFuseProducerOfSlice` that take no control function also call this tiling interface that generates the guard. However, we can just control the patterns that call these functions so can still do something like 1. 
2. is interesting can explore that to not have always working around this guard in several places.
