This makes the evaluation cache incremental. Each evaluated attribute is cached individually along with the files and environment variables it touched. When you change one thing, only the attributes that depend on that change are re-evaluated; everything else is served from cache.

When nothing changed (verified by content hash), the cached result is returned immediately without invoking Nix at all.
