Please don’t put words in my mouth — that was not my point.* I had responded to a comment that implied (1) bulk deletion is not possible; and (2) payment is required. Neither of those assertions are correct, so the actual point of my response was simply to set the record straight: (1) bulk deletion is possible; and (2) payment is not required.
I never suggested that the bulk deletion functionality would be a viable replacement for the proposed deduplication feature, only that such functionality (bulk deletion) does exist.
