Which still doesn't make it incorrect.

It's not just cutting corners that are a problem with mountain biking. Mountain biking is an extreme case ("worst case scenario") but similar issues can happen when road riding or gravel riding.
Rotation sensors using a separate magnet can have issues with the magnet not being picked up (alignment issues). Likely more of an issue with mountain biking. The newer hub rotation sensors should eliminate that issue.

No one does this.
