I'm running NixOS on some of my hosts, but I still don't fully commit to configuring everything with nix, just the base system, and I prefer docker-compose for the actual services. I do it similarly with Debian hosts using cloud-init (nix is a lot better, though).
The reason is that I want to keep the services in a portable/distro-agnostic format and decoupled from the base system, so I'm not tied too much to a single distro and can manage them separately.
