There is a limit to how far one needs to abstract personally.

I don't layer my utensils for example, because a spoon is fit for purpose and reliable.

But if I needed to eat multiple different bowls at once maybe I would need to.

For my personal use case, git is fit for purpose and reliable, even for complex refactoring. I don't find myself in any circumstances where I think, gosh, if only I could have many layers of this going on at once.
