Weaken criterion for attestation inclusion 
The invariant that `get_current_epoch(state) in [get_current_epoch(state), get_previous_epoch(state)]` is preserved, as well as symmetry/fairness across blocks.

Do not check withdrawal credentials for existing validators 
We should not invalidate blocks that contain a deposit with an inconsistent withdrawal credential as that would stall the chain.

Use hash_tree_root everywhere 
And get rid of merkle_root. This is possible because of SSZ tuples.

Fair proposer sampling 
I think we want `first_committee[epoch % len(first_committee)]` as opposed to `first_committee[slot % len(first_committee)]`. The reason is that if the shuffling happens infrequently and `len(first_committee)` is a multiple of `SLOTS_PER_EPOCH` then the proposers will not be sampled fairly.

Taking this logic further, we may want to avoiding always picking the proposer from `first_committee`, e.g.:

```
    validators_at_slot = []
    for crosslink_committee, _ in get_crosslink_committees_at_slot(state, slot, registry_change):
        validators_at_slot.append(crosslink_committee)

    return validators_at_slot[epoch % len(validators_at_slot)]
```
