> Currently the CodedValueMutationDetector[1] checks to see if the objects are Java equals
and then compares whether the bytes are equal. Instead of relying on the bytes, we should
rely on the coders structural value explicitly[2]. This allows for a coder to provide a fast
path equality check with the default still comparing byte array representations.
