Not really. The use cases for islice() typically do not involve repeated slices of an iterator unless it is slicing off the front few elements on each pass. In contrast, getitem() is all about grabbing something other than the frontmost element and seems to be intended for repeated calls on the same iterator. And its support for negative indices seems somewhat weird in the context of general purpose iterators: getitem(genprimes(), -1). I'll study Walter's use case but my instincts say that adding getitem() will do more harm than good.
