Yeah you really can't go this hands-off on deployments when the stakes are high. If someone could be physically harmed by bad code, then it all needs to be reviewed. If you can be hacked by a rouge deployment, then it all needs to be reviewed.

And more generally, it is not fun using a lot of mainstream software these days because it is a buggy mess, and I believe a lot of that dysfunction is partially related to the low standards for correctness that development teams have.
