Don't see any advantage in doing this apart from "attracting user-space developers to develop for v4l2 output interface," which doesn't seem like a worthy goal in itself. Whereas with my translation you get access to existing user-space applications and to a powerful in-kernel API, and achieve a better interoperability with video-input streams.
