> It's a modern (a 'temporary measure' enacted in WW1) invention to enact a passport-controlled system of travel and residency across the entire world.

I wonder if the same will happen to online travel pre-entry-authorizations.

During Covid many countries implemented pre-entry-authorizations, similar to US ESTA or Canadian ETA.

Even if the Covid emergency state has been over, some countries that didn't have this forms before, still require them for travel.
