Vacation Mode with No End Date
Sometimes you're not able to stream or you want to take a break from streaming, but you're not sure when exactly you'll be back. If you want to use Vacation Mode for this time, your only option is just to overestimate how long you'll be away, update if necessary, and pray people don't take that timeframe too literally.
Ideally, you could just enter vacation mode without a set end date. If there's concern about people forgetting to turn it off, it could just be auto-disabled the next time you go live.
