It probably is an overestimation of current capability. But not for lack of trying, or due to any intentional curbs put in place. And because of that, capability makes little difference when it comes to the principles at stake (at least to me) If technical limits are their only limits, the rest only becomes a matter of hurdles cleared over time.
And also, in practice, secret-selectiveness doesn't make that much difference in the ability to silence critics. You wouldn't necessarily need the data. Just the rational threat of having it.
