It's still much closer to the input machine code compared to what compiler optimizer passes do to your input C code ;)
I have empathy for this having written compiler passes for 10ish years of my career. But as I've studied register renaming, speculative branch prediction and trace caches I would no longer agree with your last sentence. It's fine though, totally just an opinion.
