It's the old copy-from moved to a task to allow for other tasks to be
executed before the image data is stored. This effort was called "new
upload workflow"[0], which intended to allow for the above but also to
avoid blocking webheads on image download.

That said, and as mentioned in other replies on this thread, I think
this is an API that would be useful for OPs not just for importing
images but also execute other "tasks". As far as the public API goes,
I don't think we should recommend it nor make it public. At least not
in its current state.
