PEP 357 gives the original rationale - it was to allow integer-like objects (such as numpy scalars) to be used as sequence indices, as well as slice parameters. I would have to grep the source to get a full list of uses, but I believe it is already used in at least those two cases, as well as for sequence repetition (via '*') and to identify permitted inputs to bin/oct/hex.
