I am in favor of separate operations too, as it will simplify future optimizations, like specification of commutativity etc.

Sidenote: I would not incline to complex dialect that much, as it might get deprecated, since there is no maintainer still. See: https://discourse.llvm.org/t/mlir-project-maintainers/87189
