-Managing plugins using the [Composer Installers](https://github.com/composer/installers) library works remarkably well. However, it's handling of MU plugins leaves something to be desired.

 WordPress MU (must use) Plugins are files that are placed in the `wp-content/mu-plugins/` folder. These files are loaded automatically. The problem is when a plugin is actually inside a folder. WordPress will only load .php files and doesn't drop into any directories. When the Composer Installers plugin runs, it always puts the repo into a nice contained folder. This means the Composer Installers MU plugins never actually run!
