One more thing, why have you removed the estimate function for API
patch? It seems to me Robert has given a different suggestion [1] to
deal with it. I think he suggests to add a new member like void
*private_data to IndexBulkDeleteResult and then provide an estimate
function. See his email [1] for detailed explanation. Did I
misunderstood it or you have handled it differently? Can you please
share your thoughts on this?
