The Xbox is a computer. It natively supports keyboards and mice. Just give up on this idea of an anachronistic “console experience” already. It’s just holding players and games back.
This is a terrible experience for people who desire to sit on a couch with a controller. People specifically use devices that spoof their keyboard and mouse a controller so they can get in queues with controller players and retain auto aim. Some games allow native keyboard and mouse support, but then they’re queued with KB/mouse players.
Not to mention, there will always be a huge overlap between ok kb/mouse players and good controller players. This leads me to believe that normal skill based matching would be enough to keep the games interesting and challenging, regardless of which control scheme you decide to use.
