Levels on handlers are generally not needed (though of course they are sometimes
needed) - level filtering should be applied at the logger first, and at the
handler only when necessary. I don't especially want to encourage the pattern
you suggest, because it isn't needed much of the time.

The code above won't do any more or less than if you hadn't bothered to set the
level on the handler.

Don't forget, more complex configurations are effected even more simply using
dictConfig().
