Here is why I believe this jailbreak shouldn't be public:
1: It cannot restore on a PC, only a Mac can. There is no way to make it run on a PC.
2: Its very very buggy
3: This is mean't for developers to test new api's.
4: it has a 58% sucess restore rate.
5: It would promote more piracy. Meaning users would illegally download the ipsw and bypass the UDID trap.
