That does fix the problem itself, but I personally believe there should be a better way of handling "optional" inputs -- "optional" because in at least some if not many cases, people would expect them to exist. Guix' emacs has imagemagick as input for instance (even though it is optional) and a separate emacs-minimal exists as the version without it and other optional inputs. I think this pattern could be applied more broadly.
