	// TODO: Separate TransactionState::Finalized, TransactionState::Accepted?
	TransactionState::Finalized
	| TransactionState::Accepted
	| TransactionState::Confirmed => {

Should the inputs of a tx only be removed form the locked_outputs if it's finalized? Because if it's happening earlier, the indexer still provides the outputs as unspent and then it could lead to conflicting txs?
Do we update the InclusionState to also have Accepted and Finalized?
Do we also need other events than just TransactionInclusion?
