Core.php can rely on composer’s autoloader now that classes are PSR-4 compliant. If you stuck to the core modules, you could even remove ClassLoader’s autoloader, but this would break any module that hasn’t been updated to support PSR-4, so I’ve left it in. In the future, it would be good to apply SilverStripe’s auto-loader only to those modules that aren’t coded to use PSR-4, as it would make class loading more predictable.
