Simplistic answer. Get all the information and in the shortest time frames, ex: in t+1. Consumers make purchases/sales for products based on reviews and the history of reviews. Why would a security be any different? You wouldn't want to transact anything if you had only a small % of information and come to find out 35 days later that the place you transacted with isn't dealing with its legal processes. When there is opportunity to be informed in a faster time frame with relevant data that exceeds what is currently provided, it should be taken.

Every share should be tracked with unique identifier. Every share should be located and lent only once. Every order should be delivered T+2 or fails mean 10x cost penalty. Every short position should be updated with FINRA daily.
