Removing it will allow you to disable auto join or forget the network, however you may not be able to connect to the password protected XFINITY network automatically. Non-passworded WiFi like xfinitywifi should still work if your device MAC is registered with Xfinity. Connecting to XFINITY WiFi may prompt for a user/pass for your account. Settings -> General -> Profiles -> XFINITY WiFi -> Remove Profile.
