@sabauma Thanks for the pointers. The Linalg constant folders are indeed sufficient.
I recreated this `tensor.pack` rewrite functionality by temporarily lowering constant packs, and then running constant folding and canonicalization patterns. Now only the op selection is custom and the rest is powered by upstream logic.

For reference, the implementation: https://github.com/plaidml/tpp-mlir/pull/921

Then I think we can close this PR to avoid duplicating functionality.
