Dependency deprecation warning: gulp-util (npm)

On registry `https://registry.npmjs.org/`, the "latest" version (v3.0.8) of dependency `gulp-util` has the following deprecation notice:

`gulp-util is deprecated - replace it, following the guidelines at https://medium.com/gulpjs/gulp-util-ca3b1f9f9ac5`

Marking the latest version of an npm package as deprecated results in the entire package being considered deprecated, so contact the package author you think this is a mistake.

Affected package file(s): `mobile-web/package.json`

If you don't care about this, you can close this issue and not be warned about `gulp-util`'s deprecation again. If you would like to completely disable all future deprecation warnings then add the following to your config:

```
"suppressNotifications": ["deprecationWarningIssues"]
```

Start with mobile-web/package.json and inspect how gulp-util is declared and used. Read the linked gulp-util replacement guidelines and check the npm registry notice; done means the deprecated dependency has been appropriately addressed and the project no longer relies on that deprecated package.
