This seems more approachable than NixOS/Guix, which I see as state or the art for declarative hosts.

One advantage this has over Nix is a simpler build toolchain. For some, that advantage may be quite useful. Even more so for the sh-based configuration management tool, rest[0], submitted several days ago.
While Guix is similar to Nix in it's higher amount of build dependencies, in theory, Guix's bootstrapping is at least elegant in comparison.
