For this page, I think it kinda makes sense as an equivalent to d:Wikidata:Sandbox, which appears to be used a few times each week, and perhaps prevents tests/vandalism elsewhere.
But I'm not sure about the linked "Zxxx, Zyyy, Zzzz" -- are those safe page-titles to set-aside as sandboxes? Or would we want them to be numbered as Wikidata does it? Or something else entirely? Quiddity (WMF) (talk) 00:38, 4 August 2023 (UTC)Reply[reply]
