To keep your analogy, most people’s git histories, when using a merge-based workflow, is the equivalent of never cleaning the kitchen, ever.
No, it’s not. And you know that.
Seriously, ask yourself, how often did the need arise to look into old commits and if it did, wasn’t the underlying issue caused by the processes around it? I’ve been in the industry for a few years now and I can literally count on one hand how often I had to actually look at commit history for more than maybe 10 commits back. And I spend maybe 10min per year on that on average, if at all.
I honestly don’t see a use case that would justify the overhead. It’s always just “but what if X, then you’d save hours!” But X never happens or X is caused by a fucked up process somewhere else and git is just the hammer to nail down every problem.
