While developing a Composer plugin I very much feel the need of a DI container.

final public function __construct(array $repoConfig, IOInterface $io, Config $config, ProcessExecutor $process = null, RemoteFilesystem $remoteFilesystem = null)

Passing all these arguments is very tedious
and accessing one instance of a class from different places is not possible automatically.

Thank you for considering.
Was #3803
