> The logged read path currently has no short read protection support, so we can erroneously return responses under the limit. Short read support needs to be adapted to work with the logged read classes. 
> The short read protection dtest is parameterized for replica types, but is only testing legacy reads, so that is a good place to start. Some of the short read tests already pass with logged reads due to the way that read response augmentation works, but things like complementary deletes do not.
