Just to pick up on a few things, certainly it wouldn't be inconsistent. It would provide greater clarity to the courts if you had that type of language; this is one factor among any number of factors that a court can take into consideration.
I think that kind of language would anticipate some of the concerns that might be raised in court by a defence lawyer, that because Parliament has not specifically enumerated these types of factors, by consequence they don't want that to be taken into consideration. That type of language provides that kind of a signal to the court that this is one of any number of factors.
