True! #84765 adds tests for `mlir-opt` and `mlir-pdll` [here](https://github.com/llvm/llvm-project/pull/84765/files#diff-b1d86cebb9a8797b8053359eace1e10cb9893f27f5bf7a7b1675c278cd3890f2) and [here](https://github.com/llvm/llvm-project/pull/84765/files#diff-91f116f16b2f7253c9d9303e370af5823398515eab34acc44e04fd8b2c503c2c) but they do not test what happens if the flag is not set at all...
