I was copying some large objects in S3 today, and ran into the "minimum throughput was specified at 1 B/s, but throughput of 0 B/s was observed" error while doing upload_part_copy using large (5GB) chunks. I was able to work around it by reducing the chunk size, but I think this means it should be added to the operationsIncompatibleWithStalledStreamProtection set like CopyObject already is.
