There are two motivations for decoupling a submodule's existence from the url that is stored in .git/config.
1. Worktrees can't really be used with submodules since the existence is checked based on the shared .git/config. This means that two different worktress have to have the same initialized submodules. By decoupling a submodule's existence from the url, two different work trees can be configured to have different submodules checked out. 2. Easily configure gorups of submodules that a user is interested in. In a repository with hundreds of submodules it would be difficult to easily tell git which modules to worry about without having to individually init all of them. Instead, a pathspec can be used to more easily select or deselect groups of submodules. This patch series works to do this decoupling and instead allows a user to configure submodule.active with a pathspec to use to check if a submodule is initialized.
