Unfortunately the benchmarking I have downstream doesn't suggest this is a great idea. Nothing gets a lot worse, but a lot of things get a little worse.
These are mostly for small in-order cores like the cortex-m55. I haven't looked deeply into why. There is a chance our downstream schedules are just getting unlucky.
