Does is perport to support name substituion?
Is this a feature request, bug report, doc fix request?
In the future please fill in the details requested in the issue template.

In any case, docker-compose is in https://github.com/docker/compose, so closing this here. Please open on the compose repo with all the relevant details.

Thanks!

I think this should be possible already if you use the name property for the network.

In that case, the name you reference the network as (within the stack) will be fixed, but the name of the actual network that's created will be customized.

Something like this;

networks:
  mynetwork:
    name: ${STAGE_NAME}
    driver: bridge
    ipam:
      driver: default
      config:
        - subnet: ${STAGE_NETWORK_PREFIX}.0/24

Inside the compose file, you'd reference the network as "mynetwork", but docker network ls will show the custom name. Take into account that that name is not "namespaced" (i.e., not prefixed with the stack name), so multiple stacks using that same custom name could collide
