They should, because the transfer is obviously incomplete if the last
empty chunk has not been seen.

It's already possible, we can add attributes on chunk sizes. We could
already have something like this to abort the transfer :


Anyway I'm not convinced by the usefulness of being able to report
this chunk by chunk, because most common aborts are due to network
timeouts and process crashes, which may happen anywhere, not just
on a chunk border. That's why closing the connection covers all
cases in a non-ambiguous way.
