I'm not sure what the precedent is here, but it should also reject for a BigInt. The test currently tests all other primitives. I presume it might be to make the test work for engines that don't support BigInt - if so maybe we can have a separate test or feature detect them?

Added a separate arg-not-object-reject-bigint.js test file with a features: [BigInt] flag so engines without BigInt support aren't gated!
