In my experience with legislation, if the intent of Parliament is to make it clear that you want that included, it's certainly helpful. For example, for the committee members when we're looking at nominations, if we see that digital creations are explicitly included, then there's no discussion about what fits and what doesn't fit and what would be okay.
There's always room for interpretation, especially in a list that says “including” because that just means here are some of the options. It doesn't mean that other things can't be included, but putting it in does create greater clarity for the program, as opposed to leaving it as a matter for discussion and debate.
