When moving a file, in most cases, the description page on the origin wiki becomes unnecessary. Could a checkbox be added (like there is on Commons Helper) which will either delete the description page (if the user has the requisite rights), or marks it for deletion (e.g., by adding the "NowCommons" template)? -Pete Forsyth (talk) 19:12, 1 February 2019 (UTC)

@Peteforsyth Thanks a lot. There's a similar request on Phabricator (T196735), and I've added your feedback there.
Best,
