Being able to edit the pending ‘post/topic’ [1] would be great though, and would really smooth out this experience for users. I think there was some talk of this in the past.
Currently the pending posts show in the post stream as well as in your /activity/pending(that page has both pending posts and topics), but you can only delete and not revise them. If they could be made editable in a similar way as the review queue allows admin/moderators to then handling the approval with ‘Revise’ could avoid deleting it and allow it to remain as ‘pending’. The feedback PM could then have a link to make it easy to navigate to, edit, and resubmit. 
There may be some rough edges to smooth out to prevent editing by user and mod at the same time, but maybe some of the new auto reviewable claiming could help with that and provide an edit lock.
There would also need to be some allowance made for the Reviewable after it had been handled as Revise, as theoretically the flag would have been handled, but would also still be pending. (And you perhaps wouldn’t want that sitting as a live flag in your review queue while you wait for an indeterminate amount of time for the revision, which may never come). 
I don’t think it’s actually a post/topic at this point, but rather a precursor ↩︎
