I would discuss this issue before hand with the person so that we all knew where we stand. And it would allow them to choose a different person if needed.
So it depends.
In the case of an elderly parent/relative, I would respect their wises. It would be devastating and disturbing to them to put them through this...needlessly. Yes it is the WT's fault that forces this, but I'm not going to add to it in this case and cause the great distress that it would. They have a right to choose.
