 **Notes and Observations**:
 
-1. There is no need for an Rc=1 variant as VA-Form is being used.
-2. There is no need for Special Registers as VA-Form is being used. 
+1. It is not practical to add Rc=1 variants as VA-Form is used and
+   there is a **pair** of results produced.
+2. An overflow variant (XER.OV set) of `divmod2du` would be valuable
+   but VA-Form EXT004 is under severe pressure. 
 3. Both instructions have been present in Intel x86 for several decades.
 4. Neither instruction is present in VSX: these are 128/64 whereas
    VSX is 128/128.
