That's true but that information would only really be of benefit to the moderators, as far as I can see, and I think we all generally trust each other enough to expect that the person submitting the information is doing their research.
I could see that once we have grown enough that we have people submitting proposals who we don't even know, that this information would be more important and needed. I do definitely expect that this system will evolve as the contributor number increases.
