We currently have an ABORT_AFTER_CONFIG constant which can be set before requiring config.php or lib/setup.php.

This is useful in many cases, but it currently stops just before adding support for the Moodle class autoloader, which is not ideal.

This issue seeks to add support for the Moodle class autoloader to requests that use ABORT_AFTER_CONFIG. This will allow more sensible class loading, even in lightweight scripts.
