I'll just add a little bit to that, if I may.
When you actually have a requirement like that, all submissions of Treasury Board and MCs are challenged by the central agencies. If there is an explicit policy requirement on that, you may see a stronger challenge function, and that should not be understated in terms of its merit as well. If you have a Treasury Board submission that Treasury Board Secretariat does not support, you're going to have a hard time going to the Treasury Board ministers.
That will be helpful as well when you look at stepping back to look at the types of instruments you can use to encourage or require the government to do certain things.
