Yesterday Fabien and I submitted the same item to the Commitfest (1859 and 1860). Unfortunately there doesn't seem to be any way for one of these to be withdrawn. "Rejected" and "Returned with Feedback" seem wrong. Ideally, there would be a way for someone who submits an item in error to withdraw it, at which point it should be as if it had never been submitted.
Meanwhile, what's the advice about how to deal with these?
Are you thinking basically another status that's "Withdrawn", but keeping it, or actually removing the records completely?
