I do find the attitude towards extra-devel and extra-testing slightly patronising around these forums sometimes - let people use them! So long as they know the risks, they can do what they want to their devices I think. If they brick them, then that's their fault. If they need to reflash, well... there's guides on the wiki!

I installed it from extras-devel or testing - can't remember which one. Slight performance issues but its pretty good. Haven't tried it with wiicontrol yet but will tonight.
