Wikidata needs the coupling between Wikipedia editors and Wikidata curation. The editors should be supported, not alienated by giving them the feeling that it becomes unmanageable for them to follow the changes (because of workflow separation, because of too many insigificant changes (like label changes in any number of languages that the average editor is unable to read).

This is great, but the solution I saw (i.e. {{#property:population|current-value=309000000}}) makes the whole Wikidata absolutely useless. The changes in wikidata items are already visible in users' watchlist, and if I'm not mistaken even in recent changes.
I'm sorry, but I do agree with Michael: we need to focus primarily on importing data and their references and then adapting the templates. This is the reason why Wikidata has been put up: to make data storage, editing, and even creating new articles easier.
Plus, just a note about seeing an item as of 2011. If I try to see what an article looked at that time and if a template in the meantime has been substituted and deleted, I'd see only a red mark stating "Template:Whatever" instead of that template. In 12 years, nobody complained about that... :)
