I see only one reason: when the change is small and you need to hang
into a function which doesnt't provide hooks, you're forced to subclass.
Perhaps it could be possible to get the same behaviour with other
solutions, but we can't say in advance.

In the case of fixed hooks, I think that only the ones described in the
previous Policy interface are certainly necessary.
