Again, I didn't contribute to that report directly, so I wouldn't be best suited to answer the question, but I think perhaps the issue that the report is getting at there is one of institutional shift.
You might potentially have these technologies used by different individuals in different parameters. Certainly, being trained in the usage of these systems can be important, but I think there's also a recognition here that unless there is some kind of set regulatory standard about what is an acceptable benchmark or an acceptable framework, you might have different jurisdictions using these technologies in different ways. On the question of what this acceptable benchmark is, again, that is outside my area of expertise. I will leave it to you policy-makers to crack that one.
I think the point being made is that if a threshold doesn't exist, it's a lot likelier that individual agencies will make these assertions themselves. There are reasons certain agencies might favour lower or higher thresholds, and this can lead to potential misuse with some of the technology.
