I'm managing my Unity 2019.3 project in git and I have a directory called `Packages` in the root of my project. In here there is a file called `manifest.json`. Is this the only file that matters in the folder or are there other configuration files that could be generated and need tracking?

In other words, is it safe to put the following lines in my `.gitignore`

    /[Pp]ackages/
    !/[Pp]ackages/manifest.json

This is very similar to [this question](https://stackoverflow.com/questions/51598430/is-it-safe-to-ignore-the-packages-folder-in-unity-2018) but it doesn't explicitly answer what I want to know.
