Piano Music, at least starting with Liszt, all the way through into the
20th century and until today.
The Ravel piece here requires five individual voices that are basically
distributed among three staves (frequent staff changes included), but
are printed partially on a three-stave PianoStaff and partially using
only the standard two staves.

I feel it's natural to use PianoStaff here and to tell it to french the
middle system if empty.
What I think I'll write to the docs now is that you have the choice
between resorting to GrandStaff (for the piano) or to remove the engraver.
