I felt the same way about KB/M, but the more I thought about it, the more I realized future spacecraft will have a variety of control options. Do you watch The Expanse? There are a few instances where it looks very much like they're using something similar to 3DConnexion's SpacePilot Pro.
TrackIR has not yet been implemented yet, but it's on our to-do list. Though, not at the top, though ... ;-)
