Yup - that works pretty well. And gives developers some insight into what is required to get stuff working.

It does assume no hardware or complex networking needs to be handled.

And there is the point of observability. When there is a proper testing ground for developers that is as-production, it enables developers to dig into and mess with logging, tracing, debugging of all sorts.

This adds value by providing developers insight into what a reliability engineer (or whatever they call sysadmins these days) needs to provide whatever service it is that the developers' code is part of.
