\brief If true, after every operation that may result in an empty relation, a check
for emptiness will be performed, and if a relation is empty, it will be deleted
and replaced by zero. This allows us to avoid performing operations that would have
no effect due to relation emptiness, but if the check for emptiness is expensive, its
cost may overcome the gains.
