   // Having the app launcher installed does not mean the user has Chrome
   // installed, or set as the default browser. The behavior for app launch needs
   // to be consistent but also respect the users default browser choice for apps
   // which appear as web sites, and never show chrome the browser if it is not
   // installed.
   // The launch behavior is:
   //   - v1 hosted apps: if chrome is not default browser, launch in default
   //                     browser; otherwise launch in chrome
   //   - v1 packaged apps : open in an app window
   //   - v2 packaged apps : launch normally
