I don’t understand. Even if Strapi is a CSR you would probably be using relative URLs and the full URL is decided at runtime depending on the server serving those static files, in this case it is Strapi.
I can also imagine that the files in /config/env/${NODE_ENV}/server.js can also be selected on server start at runtime depending on $NODE_ENV.
The only thing that comes to my mind is whether you want to produce different containers that contain minified and/or obfuscated admin panel vs. non-minified with debug symbols for dev environments.
What am I missing?
