Certainly. But the fireAllRules() would have to address a session
different from the one that's executing the consequence.

A consequence is just Java,  so go ahead.

Is "it" a fact? You can retract it from the place where it was
inserted, for instance. Well-designed rule sets don't have "cleanup
rules all over the place". And salience is a last resort, not a
first-class way of designing rule sets.
