The unused flag is suicided.  A pointer to the suicided grob still exists.

The Item class includes all grobs which represent discrete graphical
objects such as font glyphs or abstract objects which contain other grobs.
When a grob is suicided, most of its properties are cleared, including the
name, so the scheme print function defaults to the class name (Item or
Spanner in most cases).
