I would put money on the keyboard showing up in immersive environments as well, either as a small mixed reality cutout of your immediate desk area, or as a rendered 3D model if it detects an Apple keyboard. Meta's Horizon Workrooms puts a mixed reality cutout for the desk surface so you can see the keyboard, but otherwise keeps you in the virtual world. They also render certain keyboards (and whole laptops) in full 3D and show your hands on them as an alternate way of doing this.
