What are the practical reasons we should rearchitect our systems to remove NAT?

(I know the weaknesses of NAT but the cat’s out of the bag at this point...the question isn’t really “why should we use NAT”, it’s “why should we go through the pain of breaking it”.)

IPv6 does nothing to break NAT, you could deploy the exact same kind of NAT and it would have the exact same behaviour, if you really want to make your router use a bunch more memory/CPU and make it a pain for users to do anything that needs a direct connection. But you gain nothing from doing that.
