I updated the To Be Deleted page to use labels to ease curation (e.g., all of the pages that were listed had already been deleted). Now, simply labeling a page with the delete-page should suffice.
Note that prior to marking a page for deletion, to avoid breaking links in the wiki you should check the page information for any incoming links and, if they exist, edit those pages to remove links to the page that you want to delete. I’ve added this note to the To Be Deleted page as well.
The To Be Deleted page will list all pages labeled with delete-page across all spaces.
