There are multiple references, as you mentioned. I'd probably point to a couple of them.
Certainly, one of the core feedbacks we heard from partners is regarding funding predictability. My colleague from the Department of Justice talked about the role of ministers and, of course, the parliamentarians in this room in the appropriation of funds. How that works in a modern-day confederacy is important.
However, those best efforts, particularly in funding, are buffered by other things that talk about what makes water systems run. What are those true costs? How are those being assessed regularly? How are those being reported? At the back end of the legislation, you'll see reporting annually to parliamentarians, as well.
Best efforts isn't only about the language, then. It's about the intent of the subsections on funding and others, and ensuring it goes through the democratic process and is done in a transparent way.
