I agree that front end and back end should be treated as separate parts of the system (I'm not a fan of isomorphic JavaScript or server-rendered front ends). But I think that it's possible to have really good full stack developers and there is a lot of value in having one on the team. Every project needs at least one person who understands every major part of the code; the more detailed their understanding is, the better it is for the project.
