There's a greater understanding now of the risk of not being able to understand your supply chain. It's not a simple problem, because we live in a global world and sometimes you have no way other than purchasing some of your parts in places that you might not want to buy them from.
The idea is that if there is an integrator, it has to have the responsibility to examine the supply chain, identify the risks and be able to control them by inspections, testing, etc.
