yes, it would be great if that were possible. As of today, the only way to enable parallel building for all packages is to override the default for "enableParallelBuilding" in the generic builder, but if you do that you'll end up with a different stdenv. That is unsatisfactory. If /etc/nix/nix.conf would offer an option to determine the default value of "enableParallelBuilding", then we could have the best of both worlds. By default, parallel building would be enabled only for those packages that explicitly request it. For the purposes of testing and development, however, one could flip the switch and have parallel building enabled for all packages that don't explicitly disable it. In other words, users would be able to switch between opt-in and opt-out.
