Repositories options/header dropped in parallel execution

[luceos]

When having this amazing package enabled, whenever you configure a header to be sent along (eg for custom satis installations requiring authorization) the requests fail because the options/headers aren't sent along to the ComposerRepository during Parallel execution.

 Composer\Repository\ComposerRepository->loadRootServerFile() at /Users/luceos/.composer/vendor/hirak/prestissimo/src/ParallelizedComposerRepository.php:39

Example repositories configuration:

  "repositories": {
    "satis": {
      "type": "composer",
      "url": "http://local.dev/api/satis",
      "options": {
        "http": {
          "header": [
            "Authorization: Bearer <token>"
          ]
        }
      }
    }

This is a difficult problem. A composer plugin cannot know options of repositories.
Ummmmm....
