If kills don't matter, then why do you care? You can just ignore the scoreboard y'know.
This would do nothing to "lessen e-peen dicketry", it'd only make for more "I've killed more than you have!" "HAVE NOT!!!" "OMFG HAVE TOO I AM SO PRO"
This reminds of kindergarten running competitions where everyone gets a gold* medal, even the ones who were last.
*not real gold
