A feature for creators which allows for any number of options for expiring broadcasts, namely an automatic exporting system to Youtube. In short, an option to have a VOD export to Youtube on its own. We already have the option to set the privacy of a video export to either public or private, even edit the description, so keeping that option seems reasonable.
Not to speak for everyone, but a large number of streamers have dealt with problems regarding expired broadcasts that, according to some over at Twitch, may or may not be lost to the void.
Adding this feature would minimize the number of support tickets regarding such concerns and take a huge weight off of many streamers' shoulders.
