(Forwarding a request from https://ca.wikipedia.org/wiki/Viquipèdia:La_taverna/Propostes#Interwiki_de_pàgines_de_discussió)
It would be neat to have interwiki language links in discussions pages as well.
First thought: since Wikidata knows the links for the pages, maybe a gadget or so would suffice to set those _Talk links automagically, without bothering Wikidata's database.
Second thought: oh well, but not all articles have a discussion page, so we cannot reliably link to discussion pages if we don't know whether they exist or not.
Many additional thoughts:
- Could a gadget query those pages and see whether they exist or not? But this would be an expensive operation for a neat feature that in most cases would not be used...
- Should that information be stored in Wikidata after all?
- Could we just show red links for the discussions missing?
- Could 'whatever' be a good enough first approach, considering that the benefits still would outweight the cost of sending some users to discussion pages to be created?
PS: even if this seems to be a logical request, the author of this task could not find any prior task or discussion. Links welcome!
