I've noticed one thing about this feature. If a person can be responded to using this feature they don't matter. They are just some time waster bureaucrat,salesman,ect. Its actually a good feature for those of us doing real(ish?) work.
I mean, everyone realized right away that the only reason this exists is for businesses which, for whatever reason, haven't yet created an API to do bookings. So that was sort of implied from the beginning.
