Yes, the moment you construct a commit by 'git add' is the moment you review the changes you made. Very often you will find results or configuration files get added without you realising it; or you added a breakpoint() that you shouldn't commit, etc. Second, for meaningful commit messages, the commit should include changes that are related to each other. In summary `git add --all` or `git add .` should be used only after a careful inspection of `git status` or `git diff` showed you indeed need all changes, and that they belong to the same commit message.
