Yes, but that they needed to was my comment. Personally, even as a mobile developer, customizing my phone is not my hobby. I'd prefer a new foreign car that has certain limitations to a used Jeep that I can extend in any way I want.
It's not a very hard thing to do, I'm sure as a mobile developer you don't mind installing apps other than the ones that come with your phone. A different keyboard is just another app to fulfil a need, go to the Store, click install, new keyboard. Done.
Are you sure about that?
