> letting us do version control of our software with simple means instead of throwing everything at it

VCS is a pretty difficult topic, and it's not like git is the only tool out there (let alone the very first). Multiple people potentially working on the same file in conflicting ways is always going to be something that cannot just magically be made simple. After all, if there are no conflicts, "rebase" is literally the simplest command there is - just "git rebase origin/main" or whatever your equivalent is and you're good. It's only with conflicts where the fun stuff starts.
