There's also the possibility that Chrome decides to bundle this CA like Firefox mobile does, which would mean the majority of users won't have a problem. From 5.0 the builtin webview is updatable too - I think it uses Chrome's engine. That leaves other browser's such as Samsung's one which probably has the most usage, no idea if they bundle root CAs or not.
