User story: As a Wikipedia administrator, I want to delete all talk pages associated with pages I'm deleting in Nuke, so that I don't need to delete them manually and individually afterwards.
When deleting pages with Special:Nuke, only the pages created by the targeted user are deleted. This extends to not deleting talk pages for deleted pages. In almost all cases, when a page is deleted, its associated talk page should also be deleted. This generates additional manual work for administrators. We could instead provide an option to delete associated talk pages when running Nuke, regardless of who actually created the talk page.
To do this we can add a simple checkbox to the form with the text "Delete associated talk pages". The checkbox should be unselected by default. Assuming the current design of the page (non-Codex), the option should be placed between the 'Other/additional reason' text field and the 'Select: All, None, Invert' line, with appropriate spacing.
If the checkbox is selected, when deleting pages, the discussion page for each should additionally be deleted.
The edit summary for these additional deletions should prepend Delete-talk-summary-prefix to clarify the action being taken, in the same way as for individual page deletions.
Proposed design
Original description
I would like to request an addition to Special:Nuke which will add a checkbox to permit deletion of associated talk pages for any pages being nuked. There was recently a user on en.wiki which required a Nuke per policy, but their 100+ pages also had talk pages which were rendered irrelevant after the Nuke and had to be removed manually.
