Eh, I don't see it as a particularly useful feature.
Also bear in mind that adding this as a feature really is just saying "Hey look, we use our JB/CFW for pirate games!" to $ony. With that in mind, I do not think we'll be seeing this for a very long time.
I'd rather see a 1TB HDD that fits in a PS3 without having to alter the caddy myself... but that's not something the dev's can do.
