Suggestion for Nullable and Optional Order Utilities

Wouldn't it make sense for there to be

Order.nullOr

Order.nullOr

Order.undefinedOr

Order.undefinedOr

, etc ?
In many cases, one might want to sort based on fields that are nullable/optional/etc, and right now there doesn't seem to be any utility for that, although it's fairly easy to create one on the spot.
Example, my

nullableOrder<A>

nullableOrder<A>

const nullableOrder = <A>(order: Order.Order<A>): Order.Order<A | null> =>
  Order.make((self, that) =>
    self !== null ? (that !== null ? order(self, that) : 1) : -1,
  );

const nullableOrder = <A>(order: Order.Order<A>): Order.Order<A | null> =>
  Order.make((self, that) =>
    self !== null ? (that !== null ? order(self, that) : 1) : -1,
  );
