Well, surprisingly enough, one of the main reasons we use these version
control things is so that we can see *what changed*. It's a hell of a
lot easier to do this when you can just say "show me everything that
changed in the foo project between three days ago and today" rather than
having to worry about adding in extra selections to pick a project path.

And, said revision IDs are useful for keeping track of what's changed.
Or, at least, they are if you know that an update of 3 in the revision
number is equivalent to three changesets, which you don't if you use
multiple projects per repo.

One big repository is harder to work with. It's that simple.
