Comment #2 on issue 2536 by address@hidden: Patch: Make \footnote work via  
\tweak
http://code.google.com/p/lilypond/issues/detail?id=2536

Ok, here is the first problem: changing TimeSignature.  This grob is an  
indirect consequence of a change in Timing properties, consequently its  
cause is #'().

It would seem like a natural fit to forget about the ultimate_event_cause  
stuff in \tweak.  Instead, when grob types are specified, \footnote works  
as previously, possibly using a FootnoteEvent.  However, this glosses over  
the fact that \footnote _does_ receive a music argument which would then  
disappear.  It would need to be something that can disappear without  
problems, perhaps even #'() or \default.

Another possibility would be to introduce a way in which \tweaks can travel  
to indirectly created grobs, like that of \time or \clef.  That would be  
ultimately more elegant and understandable.  However, it would be piecemeal  
work.  If the first option is implemented, one can do the second option by  
and by.

Why does life need to be so complicated?
