I'm surprised there aren't any tests affected by this. Are you able to add some? Perhaps you could pre-commit them so we can see the effect on codegen introduced by this patch.

Additionally, do we expect any regressions? I have tinkered with this setting with another backend I used to work on, and I saw mixed results on these kinds of benchmarks.
