We should probably have a general cleanup of configureLink when links are not allowed to be nullptr. This causes errors to be seg faults, instead of simple errors messages like "you forgot to add the expected link X"

@marcusgillesyoung, Marcus Young, Critical: I agree with your critique of how they don't talk about the path to adoption for their system at all.
@searri, Rick Shear, Critical: Good point about the assumption of the router being safe. I feel like for a home network device especially that is not an assumption this paper should make.
