I'm not sure what the government's position is on it, because there's been no formal declaration that somehow this idea is dead in the water. It is, to your point, notably missing from the mandate letters.
COVID, I think, goes some way to explaining that. My understanding also, from talking to people in the system, is that bureaucratic resistance is first and paramount as well. Departments don't like losing aspects of their mandates to complete reorgs, and this would definitely involve that.
The combination of those two factors, I think, is a big reason we have not seen traction on it. For this type of reorg during an NSS build, and also fighter jets—and who knows what's proposed in the April 7 budget?—it would be a tall order to juggle a complete reorg while also trying to competently manage so many projects in the pipeline at the same time.
I do think, though, that it is a good idea worth evaluating and pursuing. I would always be thinking about how we could restructure ourselves to think about procurement a bit differently, and I would welcome further analysis on it.
