I think that the 'everything is a file' approach used by POSIX is partially flawed. There are certain fds that you can't interact with in the shell (I forget which, but it think it was container related). Ultimately these feel like cargo-culting and show the limitations of the POSIX model. However, a namespaced system (directories) containing endpoints (files) is a good idea. I think that dbus does a much better job of this (and it should be possible to have a tool that interacts with the system bus on the CLI). I would definitely take more inspiration from dbus than POSIX for a modern OS.
