After thinking about this for a few minutes, the author might be on the wrong track connecting this with containers. But I think there's something really there about "environmental linting". I know deep in my bones I need write access to make log files, but I don't know how many times I've debugged systems lacking this permission. I know the log path won't be known until runtime, I know the port can be specified at runtime, but I think there's a ton of room for improvement around a tool that says - hey, you're making this set of assumptions about your environment, and you should have these health checks or tests or whatever. I agree with you about this is what containers give, but I think the author is really on to something about the dev tooling and environment warning about what sorts of permissions are needed to, like, work.
