This is especially aggravating when the os inside the container and the language runtimes are much heavier than the process itself.

I've seen arguments for nano services (I wouldn't even call them micros services), that completely ignored that part. Split a small service in n tiny services, such that you have 10(os, runtime, 0.5) rather than 2(os, runtime, x).

There is no os inside the container. That's a big part of the reason containerization is so popular as a replacement for heavier alternatives like full virtualization. I get that it's a bit confusing with base image names like "ubuntu" and "fedora", but that doesn't mean that there is a nested copy of ubuntu/fedora running for every container.
