Yeah, it was released, but only for linux, and it's not really user friendly, mainly for testers and developers, you won't find a tutorial on how to do it, at least I haven't seen one anywhere.
There was actually a trick ages ago to sort of get an unencrypted hdd if I remember correctly, but yeah that was ages ago and would be patched. Marcan, you might know him from fail0verflow, was the first person I know of to truly disable encryption, but as he admits in his source code, it was a hacky way to do it (he said "horrid hack"), not desirable as a permanent solution. Anyways, this only related to linux and not to gameos, in-fact gameos wasn't even on his hdd, and the firmware wasn't on his ps3, it was a purely a linux box at the time. This also wouldn't really enable swapping hdds between ps3s.
So yeah, I think I answered everything.
