One thing that is wrong with it is that if a conforming client acquires the data with a getData call from two different sources, and they return different byte strings, then the client is permitted to signal an error and possibly break an application that exercises a blind faith in the power of "semantic immutability".

b) Some may claim that caching of LSIDs and the associated data would be impossible. But since the data is always "semantically immutable", what's wrong with caching it?
