I'd say that (1) and (2) are internal APIs, so the can simply expect `len != 0`, as every caller of that API is "under our control" and can be checked and fixed by us. But I'd say (3) is a global API and should be prepared to be called with list elements that have `len == 0`. (Keeping in mind that this case is something that will only happen under rare circumstances, someone using that API will unlikely test for that. Treating `len == 0` gracefully there can potentially prevent a lot of pain and debugging when other code than GNRC uses the driver.)
