Why does default .gitignore suggest ignoring config directory? In Drupal 8, perhaps the most anticipated feature is separation of configuration from content. It achieves this by storing configuration changes in a sites/default/config_* folder.
Why then does the default .gitignore file suggest ignoring this directory?
If I make changes to the site, I want those changes to be tracked to push them to the live site, or merged with another developer's changes.
You are supposed to put that in a separate repository, I suppose. Note that the best practice workflow is to export the configuration and git the staging directory. You are not supposed to edit the active directory to the best of my understanding.

Edit: since writing this answer the default storage is now in the database and there's no more active directory.
