I just use the debugger and it mostly works how I expect. I don’t have to go and study the data structures and other intricacies of the debugger itself to puzzle out why it works the way it does. Git is terrible in that way, as evidenced by the thousands of blog posts of people trying to describe the inner workings of it and how it will “make more sense” once you understand it as well.

Think about ZFS - ZFS works perfectly fine for me and I don't have the foggiest idea how it works beyond "copy on write" magic.
