I think that's a bad idea. The block should be marked as bad. It's not
worth losing data just to save out on theorectically marking a good
block bad - it doesn't seem to happen in practice. I'd rather lose all
of the good blocks than lose any data, so would many other people.

Sure. But it might be indicative of a problem nonetheless.
