I'd hate to be the engineer that has to deal with these requests. Not even a formal government investigation, just any number of random 3rd party researchers demanding specialized access.

* researchers, because they will have to write data access applications, including a sufficient description of planned safeguards, detailed enough to the point that their university is ready to take a legal liability (and you can imagine how easy this will be), and
* digital service coordinators, because it will take ages for them to process applications from thousands of researchers each requesting a slightly different dataset.
In the end, we need to develop standardized datasets across platforms and to streamline data access processes so that they're safe and efficient.
