Comment #9 on issue 3101 by [email protected]: Patch: Eliminates the Hara_kiri_engraver.

We don't really have a way of checking a context's idea of a grob property without actually creating the grob, right? _Should_ we be doing this?
I think that the design here should be done also considering the implementation of alternative staves, staves that _never_ appear when another staff or staff group appears.
This will require us to specify sort of an alternative suicide condition, and maybe it would have a useful relation with \neverEmpty.
