Then you're doing it wrong. My teams have two components that require review from a specific group:

1. Core infra

2. Anything related to security

Outside of those, we all can and do work on everything else. We regularly coach people in terraform and third party APIs to endure they understand that they own their application lifecycle. They control the entire SDLC and we work together to ensure sanity. There are lots of bumps but nobody gets a pass on understanding the in and outs of software development and management. I can't see a cloud based offering being successful without that.
