The changes in package.json all look good. The only changes needed are to add a test file and to make sure the new grammar is included in our scripts.

👍 good stuff @PooyaZv. We're getting ready to release soon, which means the only changes that should be merged are bugfixes. Once we branch for release and reopen main for feature work I'll take one last look and merge (probably on Monday).
