I do not yet know the mechanism for holders of 32 ETH in the future to receive actual passive income, but this is probably due to the fact that the number of wallets in excess of even such a minimum amount of 32 ETH is about 110,000. Apparently, this way the possible number of wallets to which payments will need to be transferred is reduced. Even 110,000 wallets, this is a huge job to make payments.
Of course, I would like the minimum amount in ETH to be less.
