It's entirely idempotent (which is a confusing word BTW) -- it doesn't make
any changes when no changes need to be made.

F(x) = F(F(x))

However, it does return a changed boolean because it doesn't track when the
size of the group changes.   there's a ticket about that.

Attaching a handler to a group_by, however, is very uncommon.
