I think this method would be useful for list itself (maybe tuple, but I
care less about that). It certainly should not be part of the Sequence
protocol.
I have often programmed a pattern where I .append() elements to a list in a
loop, and *expect* at least N things to make it in. In such case, getting
a sentinel answer to mylist.get(N-1) would be convenient.
Obviously, I've lived without that fine. But it's a little bit shorter and
more expressive than:
x = mylist[N-1] if len(mylist) >= N else None
