Ah yes, I came across this when someone else pointed it out as well. The project looks neat, ngl. supac also shares some goals along these lines, but dcli looks more mature. I still prefer supac (it's my project duh) because supac allows you to script in nushell, which lets you do interactive development (if you use nushell as your shell, which you absolutely should!). I also don't prefer something like YAML for config, but since it's extensible with lua, I guess it makes sense to go with a config language as well. I do think the end goals are different, I try to orient supac to be a nix alternative but with integrated package management across different package managers. Also, supac is simpler in principle because a lot of the complexity is shifted to accompanying libs in nushell (such as systemd unit integration).

Not to mention, with a couple of lines of nushell code you can probably import all your yaml configs from dcli into supac :)
