I thought you talked on the supposition of your own development environment, not about public packages that may need an older boost. For publishable expressions I agree with you. Concerning the nix expressions I use for development at my work place, I don't expect them to be much useful to other people... I'd say I can even publish them, as I use them for internal development in the company I work for. Now I'm going with the boost expression in nix... but if I want to keep the development environment I used to build a specific version of the software we do, I have to use an old copy of nixpkgs, or something like that. Maybe some expressions copied in ~/.nixpkgs will do the trick.
