I wish YouTube would allow you to have Unlisted Scheduled videos. Right now videos can be scheduled, or they can be unlisted, but not both.
If they're scheduled, they are technically private. The only people who can see them early are people who you invite to see them via YouTube's systems. Use case for Unlisted Scheduled would be early access videos i.e. for Patrons on Patreon. Then i don't need to manually release videos when early access is over
