I like to write my code to assume that it will run the same on dev and prod, but then precompile/minify prod code as part of the deployment. That is, I like to set it up like you say, but then not rely on it in production. Mainly because I want as few moving parts as possible on prod (especially if it means I don't need dev tools/libs on the production server).
