I think the misconception comes from interpreting master as a single entity. The difference with the master for a book is that copies are meant to be the same book. If your book is a modified copy of the Iliad, it is a master for its own version of the Iliad. What your describe in git is not copying, is creating new Iliads. We add more stuff and create a new master for others to make copies of. Which is the most recent master.
The reason to keep master is cost mainly. Cost of changing all the tools, hours lost trying to figure out why some script doesn't work or why some tutorial doesn't make sense. EVERYTHING has a cost. Even keeping it has a cost, a different kind though. Is it worth it? I don't really know. This article is the first time I've encountered this concern, without digging a bit more I don't know if it is a shared concerned or just someone creating a problem from nothing... 🤷♂️
To reiterate, I'm not against the change. I just think it is good to understand NOTHING is free.
