This is where the downloader saves the file to disk?
At the very least this change looks reasonable to me.

It looks like there are several places where we check for exactly save_artifact and remote.policy != Remote.STREAMED can we redefine the variable so that it already contains the streamed condition?

(Somehow this may be a copy-and-paste / missed-all-the-places-to-update bug coming from exactly there.)

Yes, original_handle_data that usually points to BasedDownloader handle_data that does the writing (if not overriden by plugins downloader)
