Of course I will be glad to provide KO feedback for you, with glowing reviews of your skills, personality, and our interactions. You are a rock-star and certainly a high potential!
I have nothing to lose by giving great feedback, but I can lose a future reference or friend by doing otherwise. I will need to collect on those references...
These things have never done any good in the ranking meetings, so it just D.O.E.S. not matter!
