Oddly I'm not able to reply directly to re-thc, so I hope you don't mind me commenting here that - I suspect that they're not deploying with a CDK-defined Code Pipeline (starter article[0], in-depth example[1]), which makes cross account/region deployments so ludicrously smooth and simple that it often has newbies refuse to believe that it can have worked _that_ easily. It is true that _some_ resources don't have L2 constructs, but there's pretty damn good coverage of the most popular services - and, even when you have to drop back to L1, that's still better than hand-written CFN templates or abandoning IaC entirely!
