Git submodules can be useful for vendoring internal parts without code duplication. It can help you if the tech you are writing the code in that repo doesn't have any specific/advanced tool for dependency management. By using `git checkout --recurse-submodules` you have a poor-man version of a package system. I'm not endorsing it as the best feature ever or as the way to do dependency management but it can be used in certain situations.
