This is a good article with a lot of good security advice, but I suggest that the Ghostbuster team and the Canada team and other core teams can communicate deeply, make up for each other's shortcomings, and finally reach the same starting point, such as reaching a compatible solution that will not cause the community to split up, only in this way can we start a main network in the whole world.
The following figure is a deployment diagram that I suggest for each BP. Each BP provides two types of nodes, some node communication with other BP's nodes through VPN(WireGuard), some use public networks to connect directly to other BP nodes， The details are decided by BP himself
