If wait listing made them money .... they would do it.
These days there is certainly the means to offer a waitlist style bid system if they wanted - just notify customers who have lodged an interest of the availablity and give them a quick link via email, text, or an app to check the price, confirm, and purchase. (Though I'm quite sure if they had a few people responding simultaneously the price would magically increase as the system picked up the multiple interest.)
