Looking at the link from Michiel, I was initially delighted, but then realizing what a hassle this would be...

First, at least I hope that the vaccinations in "Europe" will be counted as single region, otherwise I have a problem - as I am vaccinated in Slovakia, which is never going to have a VTL.
Even then I am resident in NL, so I would have to take a flight from NL? as per current reading... Maybe if they make it not "stayed in country/region of departure" but "stayed only in countries/regions eligible for VTL".

Second, all the hassle to actually travel - I count no less than 4 payable RT-PCR COVID tests (pre-departure, on arrival, day 3, day 7) and at least one day isolation (on arrival waiting for result of test) etc.
At least the insurance is not too expensive.
