This issue is not the same as T311901. Here, the pages with scans are listed in the Special:PagesWithoutScans one at a time unlike the T311901 which is repeating one single page hundreds of times.

Waited for long to be enabled on Wikisource. Since it is happening, would love to see it deploy on Bengali Wikisource too. Example - https://bn.wikisource.org/s/crl

I still see duplicated results on fr.ws.

@Bodhisattwa do you know if there is there more work to be done to resolve this?

While the issue in the above example in particular is resolved, this is a common issue for all Wikisource communities. The cause of the issue needs to be found out and resolved before closing this task.

IMHO, this is a very bad idea. There are more than one reason for that.

1. Page namespaces are for editors to proofread and NS:0 are meant for readers. This helps editors work in their own space in the background, which does not get unwanted attention from everyone visiting the site. Transferring page namespaces into NS:0 will blur the distinction.
2. The third step in the proposal (as shown in the video) adds one more click to reach the proofreading interface from index pages unlike the current system which gives direct access to the proofreading interface from index pages.
3. The books or their sub-pages are currently kept in main namespaces when they are ready for readers i.e. when proofreading is complete. In this new proposal, scanned pages not proofread with lots of OCR errors will be displayed in main namespace and will irritate the readers. Wikisource will eventually its viewers eventually when they will find bad quality contents are displayed.
4. In this new proposal, hypothetically, if a chapter which will have some existing proofread/not proofread pages and some pages which are not created at all (very common scenario), readers will get incomplete chapters while checking Wikisource. That is also bad for the viewership.
5. All the tools, lua modules, gadgets, templates etc. will have to rewritten again. That's creating another set of huge problems and it would be frustrating for the entire community.
6. Statistics will be completely broken and we will lose all our stat logs until now.
7. Deleting page namespaces will delete all kinds of editing history happening there till now.
8. The workflow of the community will be disrupted and Wikisource might lose editors because of that.

I've merged and deployed the above patch. @Bodhisattwa Can you test and see how it looks? Thanks for checking things closely and finding this bug!

I think I can withdraw this ticket as there is now another alternative for us to generate QR code.
