If you really want a deep understanding of git, it's not actually that hard to reimplement a few very basic operations in your language of choice. I'm not saying _everyone_ should do this, but it's a way to level-up your understanding. Write the porcelain for stuff like `cat-file`, `commit-tree`, `read-tree`, `write-tree`. Adding command options aren't really needed, you're not trying to actually reimplement git, you're just trying to write enough so that all of the concepts fit together in your head.
