I’m not quite sure how you would exchange biometric data with your five eyes pals in a manner that is consistent with all those lofty ideals.
Snark aside, though, this immediately brought to mind an interesting piece I ran into a little while back; about how Canadian immigration policy, while comparatively accepting on a numbers/year basis, and in terms of limited nativist backlash, is fairly carefully operated so as to discourage irregular entry; this piece advancing the thesis that this might be an important element to its relative success in terms of public acceptance of a fairly high level of immigration; but that maintaining it involves a combination of handy natural barriers and bring surprisingly picky about things like visa requirements.
This sort of monitoring move would seem to be in line with this notion.
