        Absolutely.
        That's the kind of thing I had in mind, and felt it didn't

        Some of the work has been done by the French colleagues.
        This WG should take advantage of that.

If you do that, one should also look at the "SSAC Advisory on Impacts
of Content Blocking via the Domain Name System", SAC056
