 Review comment:
   I'm picking this PR up on behalf of @sputnik13 - to respond to the last question, I checked and the unit tests as they stand right now will not pickup the case wherein the same variable was added to multiple variable groups. I can think through if / how we can catch that kind of fundamental issue with the code.
