The string context of drvPath apparently causes a derivation to _directly_ reference the whole dependency closure of the derivation drvPath belongs to. This not only is unnecessary in this case (since we are using drvHash to construct HTTP URLs which are primarily contigent on the deployed configuration and not the shape of the nix store), but also creates a very confusing derivation (e. g. web.tvl's index.html would *directly* reference pandoc).
