You can use it as a Recovery Point. Get one of those Warn receiver shackles.
Depends on the bumper. The receiver in my rear bumper is not "Rated" either, but I know it will tow a small trailer (M416) without any problem. I did verbally asked the Manufacturer before ordering it and they unofficially said the M416 would be no problem. I'm sure mine would tow way more than that, but it is made like a tank. Use good Grade 8 hardware to mount it.
I think the manufacturers just say "not rated" to cover their A**. If it is strong enough to be a recovery point, it should tow just about anything that your Jeep can handle.
