Conceptually the stats aren't directly related any particular view so
placing them as a slave would give the wrong logical association.

Technically you could implement it as a slave though, but it would tie
the stats to the particular view you made it a slave of, so if you
removed that view you'd loose the stats.

I can't answer that without reviewing the code, I'm afraid I'm too
busy to go checking.
