Sorry, I think mbm is right about this one - those who are into the click/copy instant family tree thing are not going to even think about this (and if they do, they likely will "think" that if ten other trees say the same thing - often complete with the same typos and obvious mistakes - then they are "certain" about whatever it is).

I do see how it could be helpful for one's own purposes, but I, for one, would not care what others think - there are a few researchers about my family whose information I know to be trustworthy, but since I already am in touch with them, a compilation of such stats would not add anything. Just a thought: you could put a note to yourself in the "suffix" box after the name (assuming you don't often use that) and anything you write there would be immediately viewable in any list view.
