The good 'ole days.

You're paying the tax at some point, but if that's at the start of the project it might be high enough to stop it in its tracks. A mature Rails or Django project require abstracting configuration later on in development which is a different sort of tax.

Convention over configuration absolutely has it's perils. I've unfortunately (fortunately?) hit this enough times with Clojure, I know the ecosystem well-enough I'd personally pick composition for a personal project. In a team project where composition makes collaboration difficult (generally a communication and experience problem) I'd probably choose another language with an opinionated framework.
