I thought one of the main reasons we are making Wikidata is so that you can update a value there, and then everywhere it is used will be automatically updated. If we find a more precise measurement for the depth of an ocean trench, then I just want to update it on Wikidata, and then every article that references it will be updated. I don't want to have to update it on Wikidata and then go do a null edit on every article that uses that information.

don't see what value we'd gain from storing that extra metadata. Every scenario I can think of where you care about past states of the database is already handled by the compare selected revisions feature.
If that is so simple, can the {{#property:xxx}} call in a wikipedia simply resolve to the revision that was valid at the point in time equivalent to a given revision? It seem like you say you already have the code to do that when creating the wikidata item description.
I disgree that this is an issue for mediawiki core, since it is a question of how the Wikidata-specific property function works.

PS: I admit that Denny has found an example to where an image seems to be changing in content on commons, but I still believe this is a rare case. Any wiki-statistician that can supply exact number for these cases?
