 If we're making this change (presumably, automaticTransact and
manualTransact), then it seems odd that both of them take the Transaction
interface because "apply" is required while "unapply" and "reapply" are
ignored for automaticTransact, but they're all optional for manualTransact.

Should we also split the interface into AutomaticTransaction interface and
ManualTransaction interface?
