lorddulaarsenal the way it sets up, the best performing nations in Nations League that haven't qualified through the regular qualifiers will have a play-off between themselves for the remaining spots.
It's definitely true that it's irrelevant for the top nations, but not the other ones.
Also, it's not like the alternative is no international breaks, which I'd obviously love. The alternative is just international friendlies like before, which even fewer care about.
