The Xbox Player Voice website is here, reviving a tradition we've not seen from Xbox in quite some time.
This isn't the first time Xbox has had a feature like this. The Xbox User Voice platform from many moons ago actively solicited feedback from fans and was also used to target specific games for Xbox Backwards Compatibility. The team prioritized the work (both technical and legal) based on what games were being requested the most. We didn't get all of them ... but the vast majority were eventually delivered. Xbox thus has some of the best console-oriented backward compatibility on the market.
