I've noticed within the past three years a language change and perhaps others here have, too. Most often, it's noticeable about food as in the above example. A person keeps waiting for the 'it.' The verb I've noticed most is 'come,' but perhaps there've been others.
A term for this phenomenon might be 'assumed object'?
Sidenote: there is no tag for 'rant.' Should there be? :D
