DRS is not compatible with BLT making migration not possible

[korkhau]

Describe the bug
BLT allowed for configuration overrides; for example, we had init disabled:

disable-targets:
  blt:
    shell-alias:
      init: true

To Reproduce

1. Install with composer install
2. See settings added into /default/settings.php

require DRUPAL_ROOT . "/../vendor/acquia/drupal-recommended-settings/settings/acquia-recommended.settings.php";
/**
 * IMPORTANT.
 *
 * Do not include additional settings here. Instead, add them to settings
 * included by `acquia-recommended.settings.php`. See Acquia's documentation for more detail.
 *
 * @link https://docs.acquia.com/
 */

Expected behavior
By using /drs/config.yml we should be able to disable running of /bin/drush drs:init:settings on composer install as it is in BLT

Additional context
onPostCmdEvent does not take into account any properties from config at all:

  /**
   * Includes Acquia recommended settings post composer update/install command.
   */
  public function onPostCmdEvent(): void {
    // Only install the template files, if the drupal-recommended-settings
    // plugin is installed, with drupal project.
    if ($this->settingsPackage && $this->getDrupalRoot() && !$this->bltUpdated) {
      $vendor_dir = $this->composer->getConfig()->get('vendor-dir');
      $this->executeCommand(
        $vendor_dir . "/bin/drush drs:init:settings", [],
        TRUE
      );
    }
  }
