It is about defining what the task should do. The changes of behaviour you
mentioned should be documented. In my opinion the main channel (the user) should
care about the status of the transfer task, so it should connect to the signal.
Maybe the steps are rather big and detaching from the main channel should be
done slowly (exporting some agent functions/symbols in a private header and
using them as you suggested in review for the patch 4).
