Looking at subj cheatsheet, I immediately see `git add .` described as adding ALL untracked files and unstaged changes. But deleted files will not be included, unless you pass -A / --all. But wait, that's just my memories, since git now does include removed files, according to my tests today and https://git-scm.com/docs/git-add#Documentation/git-add.txt--.... It's hard to tell if that changed in the past decade or not, cause the manual never mentions neither a version not that -A is default now in a section corresponding to -A. I still have -A in my bash aliases and it was 2017 when I finally got frustrated enough to create them.

And this complexity was literally from the first trivial thing I checked, I wasn't looking for it for hours to gaslight anyone here. Git is nice and fast as a core program, but its ui, documentation, compat and informational ecosystem are just poor.
