As a reviewer, I don't care how you got to the end result. I want to see the final code. If you settled on something in your code that was unintuitive, because you tried simpler ideas that didn't work, then note that in a comment. Comments provide the info inline and don't require someone reviewing the code now or working on the code 15 years later to read your "commit story" to understand it.

You confuse "include all the broken work-in-progress commits" with "split the independent parts that get you from A to B".
