- From the best I can tell reviewing the standard, it seems fully compatible
  to limit the target's unwind data type size, to the largest data type it
  supports; as although a 64-bit data type is defined by the standard,
  neither a host application or target could validly send, request data
  sized larger than the largest type defined as supported by the target;
  nor are large data types required for communicating smaller data type
  values, as data access is byte not unwind-word offset/size oriented.

  (so it seems fully compatible from the best I can tell?)
