Apple's App Store policies require that the Chrome browser on iOS uses the WebKit engine rather than the usual Blink, but that isn't stopping Google from indulging in a "what if" scenario. The Register has noticed that Google recently started work on an experiment that would port Blink to iOS. The project is limited to the stripped-down "content_shell" app rather than Chrome, and the Chromium team working on the effort stresses that it's not a "shippable product." It's only meant to test graphics and input performance, the company says.

In a statement, a Google spokesperson told Engadget the Blink port is only a "prototype" that's part of a larger open source initiative. It won't be available to the public, and the company will "continue to abide" by Apple's rules.
