An issued ETIAS — whether called that or not — will be required at Schengen land/seaports too, and it’s a matter of when.

Governments may claim that ETIAS (and ESTA) are merely means to carry out pre-travel screening for travellers with so-called visa-free/visa-waiver access and aren’t visas — evisa or otherwise — but they too are de facto visas in all but name.
