Just looked up Clan since I'm a big fan of Nix but currently run my cluster with k3s, which indeed has some overhead.

It seems however that Clan is one of those classic projects where the website and the docs assume that everyone already knows what it is and how it works and goes straight to the benefits of doing it this (whatever 'this' is) way.

After reading both the site, docs and guides I am now scouring Reddit and YouTube for an actual explanation of whatever the hell it is and how it works.
