Do you keep a shopping list? A personal to-do or reminders list? You should stop because that’s a ritual and rituals are clearly bad.
I mean, no, you should keep the rituals that help you work better and discard the rest. Which is what successful agile teams are already doing.
Start early in the commit history, see if you can understand the general shapes and concepts the project was using at the start.
Then sort of binary-search your way forward in different sized jumps and see how quickly you can get to present day without sacrificing your sanity. Completely at least.
