No, I wasn't trying to go that far.  Just some good natured poking.

For what it's worth, the GDB remote protocol has the same "defect".
The register array is not specified, which makes it impossible for
someone to write either a debugger or a debug agent without looking 
at the GDB sources to determine what goes where.

I actually like WDB quite a lot.  You can see it was a significant
influence in my draft RDP II spec I sent out a few days ago.
