Since we need to override random to 1.2.0 globally for xanthous (otherwise propagation causes two versions of random to be propagated for xanthous) evaluating haskell related stuff using import from derivation can be very expensive since utilities like hpack and cabal2nix need to be built for that. This means that for every channel bump we potentially need to do a world rebuild of haskellPackages first. To solve this we check in the cabal2nix-generated nix expressions for owothia and xanthous.
