It would be useful to have the possibility to provide a list of sites that are acceptable to get the reslut in. If the first does not exist, then go to the next, and so on. If no one exists, go to the Wikidata page (or use the same error message as today, but I think that should be fixed too).''
Example: https://www.wikidata.org/wiki/Special:GotoLinkedPage/svwiki/Q99999 will just give an error now. But if it could be specified like: https://www.wikidata.org/wiki/Special:GotoLinkedPage/svwiki|nowiki|dewiki|enwiki/Q99999 I would get a hit in a language that I want.
This feature would be useful for everybody that builds services using Wikidata that want to forward people to our projects in relevant languages to their target groups.
