I think they need to be considered if they are engaging in trying to influence the outcome of decision-makers. I guess the logic is why would you not include them? Again, I don't have an answer for that. They're there for some reason. They obviously have an interest in this. It may not be directly financial, but you can't minimize the impact they're having on the process. If it makes sense to shine a light on what I'm doing, surely it makes sense to shine a light on what everybody's doing.
It's really a matter of degree as to what's practical and enforceable. I think that's what the committee will struggle with.
