I'm +1 for adding test case to check this usage is valid, but IMO we should not advertise this as the primary usage of deferred completion, because unless users require ProcessingContext later in async processing, they should prefer using only
Completionso that memory pressure is dramatically reduced?There was a problem hiding this comment.
