`\Symfony\Component\Config\Resource\GlobResource::getIterator` loads files using `glob` not it the stable sorting, e.g several files: `doctrine.yml` and `doctrine_mongodb.yaml` in `config/packages` folder.
On requests these files come(randomly) in a different order, which leads to reinitialization of symfony kernel in `dev` environment. It's a little bit annoying and takes a lot of time in a common :(
