OP, while I don't like Kofi, and agree with most of your well made points, I do believe Kofi has value to the WWE. For you see, over mid card babyfaces, Ryder, Santino, Kofi, Rey are important, when used against the main event heels, in a business where the Heels find it so hard to get clean wins, and the top faces rarely lose clean, people like Kofi are ideal for jobbing to the heels, like he did Del Rio this week. During Dbry's worlds title run, the only people that tapped to him were Kofi and Santino, hence I think he has some worth in the company.
Am I the only one who reads this in Zapp Brannigan's voice? While I agree with OP's sentiments about wresterls like that, I wonder why it's directed at Kofi specifically. I'm sure there are worse people in the WWE who are guilty of this. Kofi has some wrestling skill, Otunga really cannot wrestle, and is more of a disposable commodity than Kofi is.
