The way network Access works really feels weird to me. I wish that instead i could just do it like (or with!) nix. If i know the hash of the thing I'm fetching from the network, allow me access to it. Instead of arbitrarily allow listing domains. Imagine if this would just be able to use your nix file in your repo to fetch all the dependencies needed to run your project. That'd be extremely sick
