Not to mention the time involved, the bit has to be reset in the carrier as
well.

Depends on the model, I believe. The one I have does have a diamond plated
wheel, and supposedly the ability to sharpen carbide, cobalt, TiN and
masonry bits.
But they also make the point that even the diamond wheel has a limited life,
so roughing in a broken bit on a cheap wheel just makes sense. Depending of
course on how long you're willing to work to save $.50 on a new bit <G>
