That's cool I have nothing against rooting, hacking, or simply even installing a leaked software download. Its cool and fun I'm just not big on installing leaked and tweaked software onto my phone in which I'm not sure where and how its been tampered with in the process of being leaked..I just prefer the factory settings in which the phone and os were originally designed for...I really could care less how smooth your phone runs...simply to each their own...I had a feeling this would bring attention to those who like to tamper with their phones lol...I'm not trying to debate guys...simply stating my preference.
If a leaked OTA were to be tampered with, it would fail the signature verification and wouldn't install. The fact of the matter is that 6.7.230 is an official Motorola OTA for the Bionic which simply hasn't been approved for release by Verizon. It is every bit as feature complete as the RAZR version, perhaps even a bit more polished. And if worse comes to worse, the .902 FXZ file along with RSDLite will return the phone to bone stock condition.
For instance, I leaked 5.9.905 for the Bionic before Verizon ended up approving it. That very build became the official OTA update.
Long story short, if you are concerned about the leak simply because of the possibility of tampering, with the Motorola bootloader being locked such a worry is unwarranted, because tampering is impossible.
