From the client's perspective it is almost impossible to restore deleted language links. As an example, this happened to me some days ago: 1. I saw a change to [[de:Lateinische Zeichen in Unicode]] on my watchlist, and visited the article to view it. 2. I more or less accidently found the language links missing. 3. I tried to use Special:ItemByTitle to find the item and restore the links, but no item was found. 4. I went to [[en:Latin script in Unicode]] to get the item/links from there, but they were missing there, too. 5. I had to change my watchlist to "simple" to see the Wikidata changes there, and had to go through the old changes to find the one change that diconnected the de-article from its Wikidata item. If this had happened 30 days ago, the change would no longer have appeared there. TL;DR There must be a simple way to get the item a page previously was connected to, even if it was removed from that item. Otherwise it is very hard to revert such a removal, and in an open system it is very important, that reverts are (almost) as easy as changes.
There is now a link to the connected item in the toolbox. I don't see how we can improve the situation much more so I am marking as fixed.
Such a link was present before (in the page informations), so this did not change anything relevant for this bug. This bug is about what happens when a page is removed from the Wikidata item, and once a page is removed the link to the item is no longer shown. The only way to improve the situation is to permanently store all items a page was previously connected to.
I don't think we should do this. While I understand the issue this is not the right way to fix it.
