Exactly! I explained in the article (and video) people fill the repo git ignore with all their personal tools that generate files, for example .DS_Store, .Idea etc. This should go in their personal global git ignore

Have a look at some other projects. I explained in the article (and video) the file can be pages long with every possible combination and will only keep growing as new dev tools come out

As I explained in the article, it becomes a lot of work for the maintainers, to review, check for duplicate entries etc
