That would likely be optimal.  You can use
    \layout {
      \context { \Score \remove Footnote_engraver }
      \context { \Staff \consists Footnote_engraver }
    }
to have the footnote appear only in a single Staff, at the cost of not
being able to annotate any objects above Staff level.

If one found a good way for removing the duplicates, it might even be
feasible to have the Footnote_engraver in more than one level.
