ng serve --prod throws console warnings while ng serve --environment=prod does not

[CoreyCole]

Running ng serve --environment=prod and ng serve --prod both correctly set the environment.production variable to true, but the latter dumps warnings to the console. Small problem, but it'd be best to not have console warnings on production builds.

OS?

Mac OSX El Capitan

Versions.

angular-cli: 1.0.0-beta.19-3
node: 6.8.1
os: darwin x64

Repro steps.

We created the project with the CLI after the Webpack updates were set in. We've recently started using the environment dev / prod variable.
To reproduce the console warnings, we just need to run ng serve --prod to see the console warnings and then run ng serve --environment=prod to not see any warnings.

The log given by the failure.

(when run with ng serve --prod):
