I use git history to understand wtf my colleagues, and myself, where doing and thinking 10 years ago. A well structured, squashed commit and a clean history helps A LOT. I can't tell you how often I find a 'Apply review changes' and 'Fix shit' commit with no context. I then need to go back in the blame history or find what branch/PR this belonged too on GH to find even the context of these changes. Perhaps you don't work on the kind off crappy code bases I am dealing with, but a bit of git discipline saves a fuckton of frustrations.

tbf, this says a lot more about the code base, my colleagues and the shitty, lazy culture at our company that leads to ZERO ownership and architecture ;)
