i don't yet see the use cases.

first of all.  technically, i think we could most easily implement a business key as a specially identified variable.  (i don't think an extra join in the query is a big problem. even if that would be the case, it boils down to a performance issue and not a conceptual one)

second, while i can see the value of business keys for a number of use cases.  making it mandatory is something else.  i still see many use cases that would not require a business key.  would they need to start inventing one ?  that is still not clear to me.  and just posing the invention of business key onto the user is unacceptable to me as i think this will increase the learning curve for a lot of people that don't need this feature.
