I wasn't really talking about "fancy" features of git, like rebasing history to try to make your history pretty or using things like git bisect. You need to develop basic understanding of git internals, even in the most basic workflow.
I would argue that your list of commands is not in any way complete for being "mostly good to go". At the minimum, you also need to know `git clone`, `git push`, `git pull`, `git fetch`, `git diff`, `git log`, `git blame`, and `git reset` as well. You need to save progress on your current feature branch to context switch to review some PR or analyze some production bug, well add `git stash` to the list. Your boss asked you to hotfix your recent commits onto the release branch? Better not forget `git cherry-pick`.
That brings us to 17 commands (up from the 7 you listed). Fine, it is still a finite number. Can you at least use them as a black box without bothering about the internals? NOPE. You also have to learn a lot of concepts to even understand the help and error messages for these commands - the worktree, the index, the stash, HEAD, ours vs theirs, conflicts, remotes, tracking branches.
Besides, so many commands come with their own gotchas (git checkout will happily overwrite your local changes - without any warning). Some have bad defaults, so you need to figure out which of the hundreds of options that command supports to make it do what you actually want (e.g. git log --oneline and git diff -w -b). Still others have overloaded semantics and do two completely different things (git checkout switches branches but also restores files).
