I thought about this for a while now, I currently play on Android and my Windows PC and the game is a lot of fun :), and I may be apart of a small minority, but being able to play this on my Xbox One would be pretty neat. I know on the Xbox One we have the capability to activate and launch Dev-mode on the consoles. I know there are emulators that are already published and downloadable for the said user to use by side-loading the app on the console.
PROs:
By PRO being in UWP format, it'll still be compatible with current windows platform (Tablets, Desktop, Laptop) and possibly a new way to distribute the game to the public.
Dev-kit for Xbox One is accessible to anybody that owns a console and easy to activate.
It can open the door and expands to new and current users that will play on current and future Xbox Consoles.
Consoles are controller ready, and the current game already allows controller input via the settings, which I think it would be easier to implement.
CONs:
Small minority of users that may not take advantage of their console and use it.
I'm not familiar with the difficulty to convert the game to UWP format, could be tedious/troublesome to the devs
More bugs may arise when trying to make the game compatible for the Xbox platform
I think it would be a great idea, and I hope the way of doing this isn't too difficult to develop/convert for the devs.
