Yes, found this too.
Actually it is not a bad system.
If a guest has a look at your room, for certain dates, and has not booked yet.
You can choose to trigger them to book, by offering them a 10% discount.
I just had the opportunity to offer a discount for a week at the end of November. November is almost dead, had a few bookings but it is low until the ski season starts mid december. So if offering 10% pulls guests in, I would do it.
The host can choose to offer or not, the host is not forced.
