As a course administrator/teacher, I want to be able to review the activity completion report for past students as well as current ones, so that I can provide a report to their employers/sponsors.

At the moment, when a student becomes "not current" - because their enrolment period has expired - they no longer show up on Activity or Course Completion reports.

The only way to show their data is to do a temporary re-enrolment.

There is a hack described in this forum post: https://moodle.org/mod/forum/discuss.php?d=404365

Is there any reason why this can't be included in the core code?
