The EU is currently debating exemptions for spouses who have been separated, so I doubt they have exemptions for students.
And even if the exemptions and all are sorted out, who thinks it's a great idea for a whole bunch of students to have to fly in what will now potentially be crowded planes, and then have to spend at least a couple of weeks in quarantine, for something that was not a choice of theirs at all.
Also, as if the rental/retail market wasn't bad enough, especially in college towns many of which are single industry towns, this is gonna add to even more completely unnecessary and avoidable hardship.
This is disastrous policy in every form, other than if youre someone who gets off on unnecessary cruelty.
