Description: 

In Drupal 7 and earlier, Drupal supported automatic multi-site functionality by means of different directories under the /sites/ folder. Specifically, directories there would match to the incoming domain name of a request, allowing multiple sites to be hosted in the same Drupal site. Drupal 7 also introduced a /sites/sites.php file to allow aliasing of incoming domains to specific path names.

As of Drupal 8, the multi-site functionality does not activate unless a /sites/sites.php file is present. If there is no sites.php file, then only /sites/default will be checked and no other multi-site functionality will be triggered.

sites/ABC can still be a directory and contain the modules and themes reqd for the site with its own settings.php and files folder

https://github.com/drupal/drupal/blob/8.x/core/INSTALL.txt (look for MULTISITE CONFIGURATION)

Bringing modules / themes / profiles into the root directory also removes the folder structure required for multisite if you dont want it altogether. Good work !!

For anyone who wants to save the time that I lost in discovering this:

Drupal 8 multisite and Acquia Dev Desktop

will not play together at all unless you manually copy the example.sites.php into sites.php (no change needed). Weird half-installations happen otherwise.

Drupal 8 multisite and Aegir

may have the same issues.

Both Acquia and Aegir do multisite ONLY and ignore 'default' normally. D8 now does 'default' ONLY unless the opt-in described here is applied.

It's good to force folk to get familiar with sites.php now though...
