FAQ answer unclear: filesystem size limit

I am trying to determine the maximum filesystem size on -STABLE. Assuming I
have a hardware RAID device that appears as a single 1.5TB drive, can I use
it for UFS1 on -STABLE? The FAQ is saying:

"For ffs filesystems, the maximum theoretical limit is 8 terabytes (2G
blocks), or 16TB for the default block size of 8K. In practice, there is a
soft limit of 1 terabyte, but with modifications filesystems with 4
terabytes are possible (and exist)."

Does anyone know what the modifications are, and if they are considered
stable enough for production use?
