> 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.

That's just an implementation detail. Before COVID, some countries would hand out various visitor visas to most travelers at the border, some require arranging them in advance, almost all differ in their requirements based which country's passport you hold, and based on which kind of reciprocity agreements they have with their counterpart.
