I believe so too, but it's not even that much a function of team structure. A proper design will have lots of places that are mostly self-contained at various levels of abstraction - more than people you have in your team. I believe work should be distributed among those boundaries, because it lets people agree on the interfaces and work mostly in isolation.

Also, most of the time, small self-contained units of code are trivial to fix if the original developer goes under the bus, because small means any half-decent developer should be able to read the code[0] and understand it, and self-contained means you're not afraid to change things because you can easily track how the effect of your changes propagates.
