And what are you doing when you want the knowledge of the world from 5
years ago? Isn't this a valid need? To compare what have changed for
example in the measurement of ocean depth?
These snapshots could be a low hanging fruit with valid_from and
valid_to and it is saving disk space compared to storing complete dumps
every day.
Instead of having a "List of Presidents of the US" or looking up every
person for a property "President of the USA" you could get this List
from the property "President" from the Item "USA" together with
valid_from and valid_to.

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.
