This sounds like it could become dangerous for guests. e.g. a host doesn't want to host you, but they also don't want to lose $1,000. So you show up at their house and they convince you that it's in your best interest to cancel the reservation on your end... or else.
I've had >1 Uber driver call me and ask me to cancel the request on my end because he realized he couldn't get to me for X reason, and he didn't want the cancellation to negatively impact his driver account.
