I agree that the changes are likely not extremely invasive, and I would hesitate to call them "hacks". OTOH, it does make Nixos fundamentally different from other (u)nix systems. They are basically saying it's time to hard-fork the (u)nix philosophy about how dynamic linking is done. They might be right. It's a very interesting approach, and I want to understand it in detail. I haven't had the time to bring up a Nixos system yet, though.
