Could it's use as a literal be depreciated? I haven't seen it used in that except in examples.
I take it you don't use Python for multi-dimensional array based programming, then. The ellipsis literal was added at the request of the numeric programming folks, so they had a notation for "all remaining columns" in an index tuple, and it is still used for that today. The only change related to this in Python 3 was to lift the syntactic restriction that limited the literal form to container subscripts. This change eliminated Python 2's discrepancy between defining index tuples directly in the subscript and in saving them to a variable first, or passing them as arguments to a function.
