Incopmatibility from BLT: The default value of $drs_override_config_directories is different from BLT's

[nsfisis]

Describe the bug

The default value of $drs_override_config_directories is different from $blt_override_config_directories.

BLT:

https://github.com/acquia/blt/pull/4709/files#diff-f9a40a07d9a773b708777ca2e41c24519280d8ffc19f7379b56e2587d8e389ef

if (!isset($blt_override_config_directories)) {
  $blt_override_config_directories = TRUE;
}

If $blt_override_config_directories is not set, it is set to TRUE.

Drupal Recommended Settings:

https://github.com/acquia/drupal-recommended-settings/blob/60a053a057e5b80fcb83c559ce8c5479f665eaaf/settings/config.settings.php

$drs_override_config_directories = $drs_override_config_directories ?? FALSE;

If $drs_override_config_directories is not set, it is set to FALSE.

To Reproduce

Expected behavior

According to the source code comment,

/**
 * Override config directories.
 *
 * Acquia Drupal Recommended Settings makes the assumption that,
 * if using multisite, the default configuration
 * directory should be shared between all multi-sites, and each multisite will
 * override this selectively using configuration splits. However, some
 * applications may prefer to manage the configuration for each multisite
 * completely separately. If this is the case,
 * set FALSE to $drs_override_config_directories
 * and $drs_override_site_studio_sync_directories
 * $settings['config_sync_directory'] = $dir . "/config/$site_dir"
 * $settings['site_studio_sync'] =  $dir . "/sitestudio/$site_dir" in
 * settings.php, and we will not overwrite it.
 */

setting FALSE to $drs_override_config_directories seems an exceptional case. Thus, the default value of it is expected to be TRUE as it is in BLT.

If this change is intended, it should be mentioned in the migration guide: https://dev.acquia.com/tutorial/you-dont-need-blt-acquia-cloud.
