If the current behavior is a bug, please provide the steps to reproduce.
yarn silently ignores unknown command line arguments. That's a usability problem, i.e. when users mistype an argument, the command silently proceeds but then fails to behave as expected, leaving a puzzled user. Combined with potentially dangerous arguments, this can be a bigger problem. Imagine installing an untrusted package that you'd like to inspect for security reasons, but misstyping --ignore-scripts.
What is the expected behavior?
$ yarn install --fried-chicken
yarn install v0.19.1
error Unknown argument "--fried-chicken".
