I think an increasingly common example of your "1)" scenario is when backend-heavy engineers are given frontend-heavy workloads, or vice-versa. I know I've struggled in such a situation. I say it will become increasingly common because I believe the gap between frontend and backend is growing, as frontend and backend stack choices become more complex and diverse. The breadth of knowledge required to be a true "full stack" engineer is a multiple of what it used to be. A lot of folks calling themselves full stack engineers are kidding themselves, IMHO. I don't really see folks excelling at both aspects. Usually they excel at one half (at best) and are just slapping together sloppy crap on the other end.
