The Footnote_engraver has an acknowledge_grob. Does this take more execution
time than, say, acknowledge_rest? If so, how much? I think that adding this
engraver to the Staff context as a default should only be done if doesn't slow
LilyPond down appreciably: otherwise, users can just add it themselves with a
\with { } block.
