Turning unrecognized operators into hard errors is the right instinct, but the live Wolfi aarch64 index has 69 == constraints (all libarrow==<version>), and == isn't in the operator switch. Today those resolve as "any version," which is its own bug; with this change, anything depending on libarrow fails to resolve. == needs handling as equality before this can land. Also worth knowing that #2467 replaces this parser wholesale, so coordinate with that.
