That was unnecessary. Sorry I used an S instead of a Z.

Except they don't. One of the reasons you can't put vms in multiple
regions into the same VPC is they don't have enough IP addresses to
uniquely address the backend hosts in every region. They end up with a
squirrelly VPC peering thing they relies on multiple gateway hosts to
overcome the address partitioning from overlapping RFC1918.

In other words, it proves the exact opposite of your assertion.
