Yes I was thinking about this from a customer's perspective. In particular I can't tell if Usage is buying/selling/holding reservations in their account but on their customer's behalf, or if they are just automating the buying and selling of reservations but that's all done in the customer's account with the customer's money. If the latter then if Usage disappears one day I assume you might be stuck with reservations you don't want, or without the ones you do want, but in the former scenario the situation could be more chaotic if suddenly resources you depend on simply stopped being paid for.
