If your whole company knows infrastructure well enough to build their own stuff and integrate it to existing solutions that are more or less islands of their own then you don't need a platform engineering team. PE teams are more necessary when your development teams grow to include people who don't know infrastructure or when your compliance and security requirements need to scale passed most developers knowledge. At that point the overhead and abstractions are worth it. > Now I need to write a dockerfile, loads of manifests, know about ingresses, use whatever custom tooling and abstractions they've built on top of the cloud provider. Generally speaking, on every platform team I've worked on we've been able to maintain the ability of developers to continue to interact with the raw infrastructure as code. That's a careful dance done solely for the benefit of power users. Not every PE team knows this lesson though.
