I once worked at a place that had a whole room full of such tool & die grinders. It was a custom injection molding house that had their own mold making shop staffed with journeyman and master mold makers, thus needed full custom tool making capabilities. They also had a well equipped EDM shop and full tool tempering kilns.

Alas, though I occasionally did make some personal use of a lot their equipment, I only did very minimal tool sharpening on the grinders and diamond cone wheels, so never really learned much about their advanced capabilities. I was always afraid that I'd screw something up for the mold makers who did truly depend on such equipment.
