You can make a mounted filesystem read-only with 'mount -u -r <filesystem>'. You can afterwards make it read/write again with 'mount -u -w <filesystem>'. > I think my problem is more > one of documentation.

The ufsid labels are automatically removed from a filesystem when it is mounted. So it is not surprising that no ufsid labels are found on a running system. And IIRC, the automatic ufsid labels are a new feature. The handbook might be slightly behind the times.
