I worry a little about that, because the votes and the sub-votes, or the allotments, to a large extent mirror the program structure of government. They don't mirror the purposes of government, but in terms of the program structure as delivered by departments, there's a pretty decent connection between the two.
I could see it being more detailed in the estimates, but then we get into the problem of whether or not you'll drown in detail. I mean, when the estimates used to be considered on the floor of the House, in committee of the whole, the questions used to be something like this: “Mr. Minister, last year you spent $2,500 on X. This year you're proposing to spend $3,500. Can you account for that difference?” It wasn't terribly helpful.
So I think you really have to focus on what you think members of Parliament can do, what size they'd be comfortable with.
