> just like knowing that the commits are nodes of a DAG
Hello gatekeeping! I have used Git for more than 10 years. I could not explain all of the ins-and-outs of commits, especially that they are "nodes of a DAG". I do just fine, and Git is wonderful to me. Another related example: I would say that 90%+ of .NET and Java users don't intimately understand their virtual machine that runs their code. Hot take: That is fine in 2025; they are still very productive and add lots of value.
"Intimately understand the VM" is not the same as knowing what data structure you're using. It'd be comparable to not knowing the difference between an array and a linked list. Sure you may call it gatekeeping but likewise I may call your style willful ignorance of the basics of the tools you're using. Have you never used rebase or cherry-pick?
