Thanks @rengolin  -- good thinking on extending this concept/PR. 

We need conversion from existing named to new ops in the tree (https://discourse.llvm.org/t/rfc-mlir-linalg-operation-tree/83586) otherwise we don't have that many use case for new ops .

1. named -->generic : already exists ( `mlir-opt --linalg-generalize-named-ops` ).
2. named -->  linalg.element_wise , linalg.contraction :  This PR `mlir-opt -linalg-named-to-elementwise`. We can rename it to cover contraction-op etc.
3. elementwise/contraction --> named :  Do we want this? I dont see a use case at least to me.
4. generic to named : -linalg-specialize-generic-ops  I did some work on this previously as you know but in general this path is not always possible (fused, handwritten generic).
5.  generic to elementwise/contract - I think this falls to specialize. 

We could discuss further in next Lighthouse meeting? Meanwhile, some common agreement -- e.g.
