Incompatible with this PR: #1443
post_block_update un-persists the input state in 1443

1443 is not yet merged, so we're good for now

@ozgb thank you for the notice! I made quick rebase on top of ozgb-ledger-intermediate-states and it rebased fluently, do you prefer to land your changes first? Mine are shorter, I can postpone them until you deliver #1443

Does this PR now replace #1438?
