There might be such people, but I doubt such projects would be very successful or notorious. Being able to put something on CV does not provide that long lasting gratification needed to develop/maintain software in the long run. If it's about your CV only, then there are probably more effective ways to achieve better returns.

(In my case I don't put my F/OSS on my CV and I don't think I'm "extreme minority")
