I'm trying to remember if and when we experimented with these over here?
I quite like them, it adds another layer of drama.
We've accepted the playoff format as the norm, so why not the playout?
I think the German format of the 3rd bottom team playing the 3rd placed team in the next league down is best. Serie B in Italy have a more straightforward playout with the 3rd and 4th bottom teams playing out over 2 legs.
