In future we could have giant lists, say, with 1 million of validators, so hashing it on demand may take few seconds which is unacceptable. Research team suggests to build hash for list incrementally and made a proto in Python https://github.com/ethereum/research/tree/master/ssz_hashable_list
We need to do the same thing in Java and use it for such kind of items.
