ADR-0087 exemption (already-registered): this narrows the query faces to the rule that registered entry already records: its reason states that every query face refuses a non-boolean $null / $exists flag, and its replacement is this change's whole migration (a flag is the boolean itself; $exists true is "has a value", false "has no value"). This change makes that statement true on the two drivers that did not yet refuse. No authorable key, spelling, export or published type moves, and no stored row is read or rewritten; a stored filter carrying such a flag is already refused when it is saved, by that entry.
