The majority of OpenZFS hasn't exercised the opt-out (and most importantly, the portions that are from the original ZFS are definitely not exercising the opt-out). There are two possible options: 1. Re-implement those files. 2. Ask the current copyright holder to remove the opt-out. Given how small the number of lines is[1], I would be surprised if re-implementing would take more than a few weeks.
