I think that it is not worthy the complexity to support 3d+ offsets at the core lowering.  The requirement was only to create a 2D tensor tile out of 3D+ tensor and offsets, not walking the tensor tile with 3D+ offsets. So it can be addressed by asking user to do subview upfront to 2d tensor, and xegpu only allow 2d tensor tile on top of 2d flatten tensor unless future HW relaxes it.
