None that have ever been accepted. From a quick google for manufacturer support, 9216 looks like the most popular number. But, as I said, it boils down to the largest frame *every* device on the LAN will accept. If there is a single device that only supports "9000", then that's your limit. And if there's a single non-JF device in the LAN, it throws a wrench into the whole thing. (This appears to be one of the sticking points as to why IEEE won't accept the addition of JF to any specs.)
