I think there should be promotion and relegation as that would increase the number of meaningful games hugely. And I don't think it is clear that the new system wont include promotion and relegation.
Overall the proposal is about increasing the number of meaningful competitive matches, not about commercialisation - that is a good thing. The current world game is stuffed full of meaningless matches where the only point seems to be bums on seats and ticket sales. We are at 'peak' commercialisation, we need to wrest this back towards meaningful sport.
As an example, in 2018 Wales played 12 matches, only 5 of which could be considered proper competitive matches, the rest were all 'friendlies'. And of those 5 competitive matches (the 5 6 nations games) the last 2 were effectively dead rubber meaningless encounters as Wales had, at that stage won one and lost two so there was no chance of winning the 6 nations, nor any concern about relegation, nor any value in finishing second rather than third.
