Note we should not remove await_prepared_transactions_on_FCV_downgrade.js and abort_unprepared_transactions_on_FCV_downgrade.js as they are not specific to upgrade/downgrade between 4.2/4.0.

These tests cover current locking and transactions behavior. They are not feature requirements and are free to be changed/updated once we have made a conscious decision to change these behaviors.
