Just to clarify, I'm not against changing this value if it's beneficial, since https://github.com/llvm/llvm-project/pull/71166 was a bit of an experiment anyway.

It sounds like from the comments (rather than the commit message) that you are worried about code size? If so, I can certainly understand that point of view. Like @ilinpv suggested I believe we already use a lower value for -Oz and can extend this to -Os if that helps? Or if you believe this patch has no effect on performance at -O3 perhaps we could just change the default at all optimisation levels.
