There's No Shortcut to Proper Planning

If I understood correctly, these costs should incur only when using cross region shortcuts, right?

If I use the same strategy to segregate different capacities on different workspaces and connect then by a shortcut, should I expect bandwith costs even if the 2 capacities are on the same region? Since is the same data, on the same one lake on the same region, I expect that the answer is no.
