> I can install any keyboard I want as long as it's just a skin on their keyboard.
As an iOS app dev with a hobby project iOS keyboard, this is false. Third party iOS keyboards have just as much control over the keyboard UI and how each key (if it even has keys — your “keyboard” can be literally anything) interacts with text as a full fledged app does. In fact there is no way to “skin” the standard keyboard, but I wish there were because building a decent touch keyboard is actually quite difficult and that’d reduce the workload quite a lot.
