I do remember now. It was about container-to-container-communication: having FQDN is awesome because it helps you not to care about quirks of localhost:PORT everywhere in your code (SSL out of the box would be great, though). The problem is that, other than real world FQDN, the domain name of container A is not available inside of container B. This breaks frontend frameworks like next or nuxt which combine SSR on the first page load and do CSR on subsequent request: on the server, the API domain would be `host.docker.internal` and would need to change to `http://api.orb.local` for the client side. The docs didn't make this clear, so at first, I refactored everything to use the orbstack url, just to return back to the mix.
